The IP Address Survival Guide
The fundamental method for computers to identify themselves on most computer networks is through the help of ip address. Every computer (or other network device) connected to the Internet has an IP address. IP addresses are written in a notation using numbers separated by dots. This is called "dotted-decimal" notation, for instance 10.0.0.1 and 192.168.0.1 are some good examples. Everyone who needs to use a computer network should understand how to look up their own IP addresses. The exact procedure to follow depends on the kind of computer you use. When a computer network is functioning properly, IP addresses stay in the background; however, the common problems like the following may arise:
• A computer has no IP address
• Two computers have the same IP address
• A computer has a "bad" IP address that won't allow it to "talk" on the network
These problems can be solved by IP address release / renew, setting static IP addresses, and updating the subnet configuration. Moreover you can also hide your ip address in order to increase your privacy on the internet.
