Re: anybody know the owner of 209.251.0.0/19?

If you check arin whois, you can find ip block  209.251.0.0 - 209.251.23.255
listed as NETBLK-SISCOM-BLK-1 (why would ARIN assign them /20 + /21 but 
not make it easier for everyone and just do /19 ?????????):
[whois.arin.net]

Not surprisingly SISCOM.NET (AS11036) is announcing this as /19, I'd do the 
same if I were them.... Now I don't know anything about SISCOM but it does 
not look like they are out of business or controlled by spammers, so I 
think it would be best to just contact them on this issue (and ask them to 
talk to ARIN and add extra /21 to their allocation to make it even /19)
