    You can get a list of domains the DNS resolver is going to search from /etc/resolv.conf

    $ cat /etc/resolv.conf 
# Generated by NetworkManager
search anon.local int.anon.co.uk
nameserver 10.201.13.10
nameserver 10.213.13.10
nameserver 8.8.8.8

    In the above there is search directive with a list of domains to search. So, when you try to resolve hostname X, it is going to search for X, X.anon.local and X.int.anon.co.uk.
