Here's a quick and dirty trick: |
| 13 |
|
| 14 |
$host skynet.be |
| 15 |
skynet.be has address 195.238.10.70 |
| 16 |
|
| 17 |
$whois -H 195.238.10.70 |
| 18 |
<snip> |
| 19 |
% Information related to '195.238.0.0 - 195.238.31.255' |
| 20 |
inetnum: 195.238.0.0 - 195.238.31.255 |
| 21 |
netname: SKYNET-B |
| 22 |
descr: Belgacom SA/NV |
| 23 |
descr: Internet access provider |
| 24 |

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