DNS stands for Domain Name Service, Server, or System. It translates domain names to IP's. So, if you want to go to say, yahoo.com, a dns server would translate yahoo.com into the ip, which is 66.94.234.13. The reason it does this is because the internet has always been based on IP's, and when it got hard to remember all of the IP addresses they decided to make up DNS.

An IP address is a 32 bit sequence of four numbers that are sepparated by periods. Each number can be 0 to 255. There are 3 types of IP addresses. Class A, which supports 16 million hosts on each of 126 networks. Class B, which supports 65,000 hosts on each of 16,000 networks. And class C, which supports 254 hosts on each of 2 million networks. ARIN, RIPE NCC, LACNIC and APNIC all assign IP addresses of these 3 types. These will soon be replaced by CIDR, a new system that will replace the system of assigning IP addresses now that are running out of free IP addresses.

The information is good except that IP numbers can run from 0-255 and not 1-255. Other than that, I really cant see how any of this could help anyone do anything without explaining subnet masks, default gateways and how to configure such. Ip isnt going anywhere either. It will be used in conjunction with IPv6. It will give us something like 1000 IP addresses per square foot over the entire earth. Anywho, thats my 2 cents...
