Network Address Problems

A network address is the unique identity of a computer that belongs to a network. This address helps computers to identify each other and communicate with each other through messages. A common kind of network address is the Internet Protocol (IP) address which has four bytes or 32 bits. Media Access Control is another popular network address that consists of six bytes or 48 bits that are burnt into the network adapter. Given below are a few questions answered by the Experts on network address related issues.

What do I do to get my network address?

To find the address, go to “Start” and select “Search”. Once you do this, type in “CMD” and hit enter. You will notice a command line icon that will appear in the left pane. On the icon, right click and select “Run As Administrator”. Type “ipconfig/all” when the command line opens and hit enter to get your network address.

I have an IP address that is 192.168.1.25 and a subnet mask of 255.255.255.0. How do I find out my network address, host address, number of hosts, and broadcast address for the network? Also, how can users on this network use the internet?

Based on your case information, the details you requested are given below:
Network Address: 192.168.1.0
Host Address: 192.168.1.25
Number of hosts: 256-2=254 hosts
Broadcast Address: 192.168.1.255

To connect with the internet, you will need a gateway that can turn the private addresses on your private Local Area Network into a public address. You can do this with the help of a router using Network Address Translation (NAT) that enables online communication through IP addresses and port numbers.

I am hooking up my laptop for the first time and don’t know how to get a network address on my existing router. Please help.

Case details: Re-booted modem; re-booted router (Linksys); hard wired into router currently. No issue connecting to my neighbor’s wireless but want to get online using the wireless router.

To begin with, go to “Start” and then click on “Run” and type “CMD”. Once a dialog box opens, key in netsh winsock reset catalog. After that, key in netsh int ip reset reset.log and restart your system. It should work.

If it still doesn’t work, run the commands once more and restart again.

In case you are still facing a problem, go to “Start”, enter the “Control panel” and click on “System”. Then, visit “Device Manager” and get your ethernet adaptor uninstalled. Restart the system and install your adaptor once more.

Sometimes, what also happens is that your firmware for your router may need to be updated. You can download the firmware update for your router from www.linksys.com/download/

Once you have done this, get your computer connected to port 1 of the router. Keep the modem disconnected and switch off the computer. Then locate the reset button at the back of the router, press and hold it for 15 seconds and release it. After 60 seconds, switch on your computer and key this address in: http://192.168.1.1/

When a login screen appears, enter both the username and password as “admin”. Once the computer logs you in, click on “Administration” and then select “Firmware Upgrade”. Click “Browse” to choose the file you downloaded earlier and finish the upgrade process. While this is being done, make sure you don’t disconnect the power to your system.

If you need to create 2 subnets from the Class C network address: 192.168.89.0, what is the minimum number of bits that you would need to borrow?

In this case, you would need to borrow 25 mask bits.

Network addresses can be of two types: private and public. If a computer has a private address, it won’t be able to access other computers or resources that lie outside its network. If it has a public network address, however, it can transmit and receive information beyond its local network. If you need more information on network addresses, get in touch with an Networking Expert who can offer you quick solutions to help with your case.
