How to Change Your IP for Diablo 2by Lindsay HowellUpdated September 22, 2017
Diablo 2 is a horror/fantasy PC game in which a person can battle monsters, fallen angels and other enemies. Diablo 2 can be played on Blizzard's online service Battle.net so that players can join up and battle alongside others. If your Internet protocol (IP) address is blocked on Battle.net due to a connection error or a technical problem, you can use the Windows command prompt to reconfigure your IP address and sign back into Battle.net to play Diablo 2.
Close out any running programs or applications on your computer. Open your computer's "Start" menu and click on "Run" to open the command prompt.
Type in "Command," which will bring you to the DOS prompt screen. Type in "ipconfig /release" and hit "Enter."
Type in the command "ipconfig /renew." Your new IP address will appear in the display. Type "Exit" to close out the command prompt.
Go to Battle.net and sign in. Your new IP address will be the one that is recognized.
A blocked IP address on Battle.net does not mean that your account itself has been blocked.
