How to set a static IP in Windows 7 (TCP/IP Settings)

Implicitly (default) when we connect to Internet - whether it's a cable or one wireless - IP addresses are distributed dynamic by ISP (Ie, the connection is made through a Dynamic IP). Use dynamic IPs is practiced by most Internet providers because it requires no configuration, network connection being made in a automatic. Every time the connection is restarted, the ISP router assigns the PC a IP address available (which has not already been assigned to another computer in the network), most likely different from the IP it had before the restart.

When the connection to the Internet is made through the same IP, regardless of how many restarts of the computer or the connection take place, the respective IP is called Static IP. Not recommended quitting dynamic IPs in favor of the state than in case you have by contract (or other long-established means) of one or more IP addresses that you know for sure that the ISP to which you are subscribed to incorporate them the group dynamic IPs (router will not know when or if a computer will use a specific IP address and it is possible to assign the same address to another computer in the network, leading to unable to connect to the Internet both computers).
