That's not what I meant. Imagine you're working on a computer named
"myhost.mydomain.com" with the given IP "165.89.3.54", I want to check
if strings like:

myhost
myhost.mydomain.com
165.89.3.54

corresponds to localhost, it means the computer you're working on.
My final goal is to replace the given hostname with "localhost" if
the hostname is effectively localhost, and keep the hostname otherwise.
This is to avoid to perform inet connection if the host is local
(this leads to various problems with CUPS server under SuSE default
config, which refuses any connection except those coming from
127.0.0.1).
