Here's a quick and dirty trick:

$host skynet.be
skynet.be has address 195.238.10.70

$whois -H 195.238.10.70
<snip>
% Information related to '195.238.0.0 - 195.238.31.255'
inetnum:        195.238.0.0 - 195.238.31.255
netname:        SKYNET-B
descr:          Belgacom SA/NV
descr:          Internet access provider

As Paul said, though, asking them is more accurate.
