IP address stands for "Internet Protocol Address" and it is this number that identifies your computer on a network or on the Internet. The IP address essentially allows one device to communicate with another on the network with each device having its own unique IP address. Static IP address, unlike dynamic IP addresses never change. Sometimes your computer disconnects from the network. It then has problems reconnecting. Resetting or renewing your static IP address will usually resolve such issues and involves a simple process of accessing the command prompt and typing in a few commands.
Click on the 'Start' button located in the bottom right hand corner of your windows Task Bar. Review the menu that pops up, locate the 'Run' option, and click it on.
Type in the letters 'cmd' into the text box appearing onscreen, and make sure you only type in only the letters, leaving out the quotes.
Type 'ipconfig' at the command prompt, minus the quotes to, determine the status of your current IP address. If the system comes back with an IP address, type in 'ipconfig/release' to release the IP address. If not, continue to the next step.
Type 'ipconfig/renew at the next command prompt to renew or reset the IP address.
Keep in mind your static IP address with not change, but only renew. Only dynamic IP addresses may change. If you want to change your static IP address for some reason, you will need to contact your Internet Service Provider (ISP) to find out if the provider is willing to change it for you. Also, keep in mind that most ISP's will not honour such a request. Static IP addresses make the process of detecting specific devices, easier across a network. These types of IPs are often used in online gaming environments, by ISPs, VOIP (Voice Over Internet Protocol) devices, or in almost any environment whether where quick and easy location of a computer or device is crucial. For these reasons, sometimes static IP's garner a reputation for lacking in security; however, by using sound security procedures while surfing the Internet will mitigate such risks.
