it should be something like:
search univ-orleans.fr
or
search my.local.lan
if your IT has defined it for 192.168.x.y

that's expected if your private non routable network if managed by a dhcp server.
Check:
/etc/sysconfig/network
/etc/sysconfig/network-scripts/ifcfg-eth0
/var/lib/dhclient/dhclient-eth0.leases 

What does:
$ ip  -f inet6 addr show eth0
Just to be sure that you don't have ipv6 enabled ;)
