Walking Through Networking Fundamentals

There are a few basics one must understand before you change IP addresses. Your computer’s IP address is assigned to you from your Internet Service Provider. You can either get a static IP address or a dynamic IP address. Simply put, you are assigned either get one or the other depending on the account you signed up with.

Dynamic IP addresses are addresses that are random and change after a specific amount of time. Static IP addresses are permanently assigned to you from your service provider and do not change. Usually, if you sign up for a business account, which is usually more expensive, you’ll get a static IP address. With a business account you’ll usually have to call your service provider to change IP addresses.

As you might have guessed, since dynamic IP addresses are randomly assigned, you won’t have to call your ISP to change IP addresses. You can try the suggestions we have below to get a new IP address.

Changing IP Addresses over a PPPoE Connection

Simply put, if you have to log in with a user name and password to connect to the Internet then you have a PPPoE connection. To change IP addresses with this type of connection, all you need to do is to log off and log back in. Every time you log in you are assigned a new address.

Changing IP Addresses over a DHCP Connection

A DHCP connection, in layman’s terms, is the opposite of a PPPoE connection. You don’t need to log in or log out to get connected. All you have to do is to turn on your modem and then you are assigned an IP address automatically. To change IP addresses over this connection all you have to do is to power cycle your modem.

Changing IP Addresses in Windows

To get a new IP address in Windows, right click ‘My Network Places’ or ‘Network Neighborhood’ on your desktop and click ‘Properties’. Then, right click on ‘Local Area Connection’ in the next window and select ‘Properties’. You then click ‘Internet Protocol (TCP/IP)’; in the next window and click ‘Properties’. Select ‘Use the following IP address’ and fill out the numbers for the boxes in this window. Click ‘OK’ on this and the next window. Repeat the same steps except that you will select ‘Obtain an IP address automatically’ in the Internet Protocol (TCP/IP) Properties window.

Changing IP Addresses in Linux

To get a new address in Linux, you start by going to the command prompt. You then move to the directory /etc/sysconfig/network. Your next step is to adjust your network settings in the interfaces file.

When tracing an IP Address, you can collect some basic data regarding the computer it has been assigned to, for example: location of the computer, the Internet Service Provider (ISP) responsible for the connection, the type of connection (Cable, DSL, Dial-Up, etc.) and more. Fortunately, you cannot obtain a specific address for the computer behind an IP Address, but you can determine a location as specific as the city it’s located in!

Let’s take a look at the first IP tracer on our list: IP Adress.

Available Features: Internet Protocol Address, Country and Country Code, City and State, Postal Code, Latitude and Longitude, Internet Service Provider, Proxy, IP Host Name, Local Time, Internet Speed, Browser, Operating System and Referrer. This site also displays a Google Map image of the city.

Design: The website is cluttered and houses tons of advertisements that may distract the visitor or draw them off-course. However, the information is nearly centered and is completely above the fold, so you won’t need to scroll down the page to see anything. The box in which to type the desired IP Address is extremely easy to locate and the site offers simplistic navigation in a very straight-forward manner.

The second IP tracer on the list is: Find IP Address.

Available Features: Unfortunately, this site offers less in the way of features. It displays: Router Internet Protocol Address, IP Address, Host Name, Country Name, Continent, Latitude and Longitude, Country Code, City and State, Internet Service Provider, and Time Zone. It also interfaces with Google Maps to bring you an image of the city.

Design: What this tool lacks in features, it makes up for in design. You won’t find an annoying cluster of advertisements surrounding the information. It’s much cleaner and more user-friendly.

Finally, the third IP tracer is: My IP Test.

Available Features: This tool provides you with the IP Address and offers a feature where, with just one click, you can see whether or not the IP Address is blacklisted or you may examine the WHOIS data. It also displays Proxy Information, the ISP, Host Name, City, Country, Country Code, Latitude and Longitude, and the State. This site also displays a Google Map and comes with the unique ability to link directly to the results of a specific IP Address.

Design: The data is displayed exactly where your eyes would look for it first. The only advertisements are located at the very bottom and are barely even noticeable. This provides the visitor with an overall better experience and faster loading times.

So, as you can see, each of the tracers offer their own pros and cons, but have the same core functionality. Thanks to sites like these, tracing someone’s IP Address to get more detailed information is as simple as just a few clicks!

Characteristics

This IP address is the one being used by the LinkSys broadband router. It is an IPv4 and is classified as private. It is very similar to other private addresses. Although it is used by LinkSys, it can also be utilized by other computers on a network.

Usage

If you are going to use another computer or node with this IP address you should make sure that only one avails of it. The address can only be utilized by one computer. If you set two computers with this address it can lead to problems and conflicts.

If you are running a network, this 192.168.1.1 setting must be changed by the administrator or other qualified personnel.

Advantages

While only one computer can use this IP address, it can be harnessed in different networks. This makes it very attractive to use on networks. Keep in mind though that it cannot be used on the Net without the NAT. This is the Network Address Translation. When using this utility it becomes easier to manage the router.

Broadband Routers

A lot of the information about this IP address can be found in user guides for broadband routers. These routers are not just applicable in networks. They are also used in games as well. It is also used by DSL and cable connections. Using this address it becomes easier for the network to manage the data flow.

Again the 192.168.1.1 can be altered by the user. Most of the time, it will just require getting to the web browser and providing the correct information.

Efficiency

Repeat passing is possible with this address. This feature, combined with its ability for use on multiple networks, make it an attractive choice for most systems. Aside from being a router, it can also act as a gateway.

This function allows it to facilitate the flow of information more easily. Ordinary users probably don’t have to worry about the gateway function at all. It can be looked at as a turnpike whereby the data flow is represented by the rushing traffic.

Troubleshooting

If there are problems in the router or network, the 192.168.1.1 can be a good place to look for answers. Start by going to the main controls. By logging in you can access its many controls. Among them are the username / password and network components.

You can adjust various settings here. Among them are the DCP and local / wide area networks. The modem and other communication facilities are also included here. If you are having trouble with some controls, this is the place you can look for answers.

Owing to its complexity, the functions here should be left to experts. The system administrator and qualified people should handle and oversee these controls.

The 192.168.1.1 IP address does its job without fuss. Most of the time you wouldn’t even be aware of it. But it’s good to know its functions in case something does happen.

The Role of the IP Address

All computers have IP addresses. These are used by networks or servers to identify it. This particular address is categorized as an IPv4 private line. This private line is currently being used by Belkin for their broadband routers. When you check the home page for the router, it’s the default IP address installed.

How it Works for Routers and Networks

Because it is the default address in the router, it’s become the standard by which data is processed. The 192.168.2.1 address works with the routers and networks in complex ways.

A simple way to describe it would be that it holds data. For example, information is requested from the Web. When the request is sent, this IP address works with the nodes to facilitate the action. The Network Address Translator helps it make sense of the information being processed.

This is only aspect. The broadband routers are also utilized for stabilizing online connections. In multiplayer games and other network functions, it is used for processing the information bits.

Changing the Settings

It’s easy enough to change the password or username. Just log in to the home page and make the alterations (the address is 192.168.2.1 if you haven’t changed it). Aside from user accounts, it’s also possible to change several other functions. If you’re on a network, you can also modify the modem, DSL and other communications settings.

Troubleshooting

There are a few problems that you might run into. If you run LinkSys and forget the password, you can reset the broadband router by resetting the button. If there is a problem with connections, go to My Network Places. Go over the properties in the LAN or TCP/IP. These are the places to check if you have problems with your connections.

Other problems can be attributed to firewalls. The actions of 192.168.2.1 and the router / network can be affected by the firewalls. If you’re a user, consult the administrator before attempting to turn it off.

Tips

• Always have the installation disk with you at all times. Some problems can only be resolved by reinstalling everything. For this reason, you should make it a point to have the disk, manuals etc with you.
• Take the time to study broadband routers if you’re going to use them. You can’t just expect things to work out properly all the time. Even if you follow all the directions, problems can happen. If you know how it works, you won’t have to call technical support. At the very least you can be of help to them too.
• If you don’t know how to fix the problem though, don’t force the situation. Tinkering with controls you don’t know how to use can be dangerous.
• It’s not easy to learn all the facts about 192.168.2.1. But the knowledge can pay off when some problem comes up.

We will define what 127.0.0.1 is in the discussion below. We will also go over some computer networking basics so that beginners may understand the uses of this string of numbers. Finally we’ll go over the uses of this series of numbers and how it helps you troubleshoot your network connection.

The Loopback Address 127.0.0.1

127.0.0.1 is otherwise known as the loopback address. This is also an IP address that is designated to a computer on a network. Every computer on a network should have a unique IP address so that it can be identified on the network. As with IP addresses, the loopback address also specifies which computer should receive a requested packet of data.

However, the loopback address is categorized under a special group of IP addresses that will not usually be assigned at random to computers on a network. Defined by RFC 3330 by the Internet Engineering Task Force, this address along with 12 others has been designated for special purposes.

This simply means that no computer on any network can have an IP address of 127.0.0.1. If a router or any other network gateway gets a packet intended for this and other special address, that device is required to drop that packet.

The Purpose of the Loopback Address

The name given to 127.0.0.1 also gives its purpose away. The term ‘loopback’ already hints at the purpose for this address. This IP address refers the very computer sending out the packets. For example, you type the command:
ping 127.0.0.1

Your computer will send out four packets and will receive four packets in return with a 0% loss report. This simply means that your computer sent out four packets of data to itself and received all four packets back, thus the name for this special address.

If you get 0% loss on this ping request then you know that your network interface card is working. You also know that the drivers for that device also work and that your computer’s TCP/IP is functioning as well. As you might have guessed, this special IP address is primarily designated to test your own computer.

Basic Definition and Function

This IP address is set right after 192.168.0.0. Along with a few others, it is recognized as a private type. There are several elements that distinguish it from the other addresses. Its most obvious characteristic is that it is being used by several companies. Its main function is to facilitate the use of the broadband router.

The Broadband Router

The broadband router has many uses. It plays a vital role in making home network be more accessible. At the same time the 192.168.0.1 enables broadband or cable connections. Other components of the router make it critical for online games, using cable modems and other similar communication devices.

Flexibility

There are several reasons why this IP address is used. One of them is that it removes a lot of the hassle of assembling various components. By using this address, there’s no longer any need to install separate DHCP servers. The need to install numerous other switches is also removed. With the router using this address, the router will be sufficient to perform all tasks.

Part of the 192.168.0.1 flexibility is that it can be changed easily. For a system administrator, it’s just a matter of changing the address at the default Web browser.

Troubleshooting

A lot of potential problems can be avoided if a few basic things are kept in mind. First, a solitary device can be attached to it. If another one is used with the same address, it can adversely affect the entire system. Depending on the network system, there may be other components that should be added.

If you’re the network administrator, check with the right personnel. If you’re setting up the router, read the user guide. In any case, make sure that setup and use is restricted to the right personnel.

Another reason to restrict access is that it is where usernames and passwords are changed. As an administrator, keep the system under control by keeping access limited to only the proper people.

Other Facts

Here are a few other facts about 192.168.0.1. While attachment is limited to one device, it can be passed often. This means it can be used on several networks. This feature makes it very attractive for use with multiple LANs (local area network). The IP address also makes for a good gateway.

The gateway allows subnets to exchange information with one another. These can exist in either networks or Internet connections. The best way to visualize this is to imagine a highway where information goes through. The gateway is where the information travels.

When you set the network up, you can also use the IP address to assess the DHCP settings. Most would look at this spot first if there’s suspicion of hacking. Modifying modem settings is also done here.

There are many other functions of 192.168.0.1. As an administrator, the more familiar you are with it the easier it will be to manage your network.
