There's a 'report-host' option that can be set in the conf file to
mask the host name. Sounds like this may be set.
If you want to get the server's actual host name from within mysql,
how about running a system command:
mysql> \! hostname;
or
mysql> \! cat /etc/hostnames; (debian)
mysql> \! cat /etc/hosts; (CentOS/rhel)
