The standard one in Linux distros may only have the 127.0.0.1 address listed as "localhost." The standard one in Ubuntu-derived distros is a little longer, but not all that much.

Another way to do this that is safer for any IP address that might
change is to set up a caching DNS server then point all of your
computers to it first then secondarily to your current DNS. I changed
the DNS settings in my router to point to my caching server first.
