Network 101

What is you IP address?


Since you are using the Internet at this point, you are at the least using two IP addresses. If you are into a small network (home or small office) you might get the following;

1. The local IP you probably obtained from the DHCP server which is another feature of your DSL MODEM (so it may be a DSL MODEM/Router/DHCP server). If you have a separate router it may also be a DHCP server. It usually has this 192.168.x.x IP address which is commonly used range of IP for small networks. This is also true in most wireless broadband provider (e.g. Smart bro, etc. ) Type ipconfig on your command prompt to display your local IP.

2. The public IP your DSL MODEM obtained from your ISP. This is public and can be viewed "publictly". To see your public IP, copy paste this http://whatismyip.com/ and voila, it will display the IP obtained. In some cases though and especialy if your office has a web server, you might have static(fixed) public IP which was given by your ISP. In this case it is not obtained, meaning you will get the same public IP all the time.

I will explain this further on my future post. For the meantime, I will go visit the City of Tayabas.
