[xwiki-users] Changing of the localhost

On my first try, the Windows command prompt gave http://idea-PC:8080/ as a directory of my wiki. The next day, the command prompt gave me a different directory which was http://tonec.com:8080/, although I can still access the first directory given to me. I prefer using the first directory, since tonec.com is related to other software (the program might have made a mistake in choosing the directory). How can I make the default directory back to the first?
