At 7:45 PM -0400 8/20/02, Stefan Jeglinski imposed structure on a stream of electrons, yielding: >My IP block is 63.220.231.128/26, and my upstream ISP is >(supposedly) Network Access Solutions, aka nas-corp.com. > >I can see that ours is part of a larger netblock ultimately owned by CAIS: > ><http://ws.arin.net/cgi-bin/whois.pl?queryinput=NETBLK-CAIS-CIDR7> > >However, I cannot seem to find which sub-block including mine is >owned, maintained, allocated or otherwise run by nas-corp.com.

Can someone help me clear up this mystery?
It doesn't look like the janitors at CAIS (all that are left after their bankruptcy and subsequent asset acquisition, according to rumor...) have managed to get the block you are in sub-registered to NAS. NAS is likely not to be really focused on getting that detail handled, given their own bankruptcy. As to the issue of how to determine that, a whois query on any ARIN IP address at ARIN will kick out the whole hierarchy of registered blocks. For example, 66.73.230.190 returns my name (and some address SBC uses for all their customer sub-registrations) on my /29 and Ameritech's name on the enclosing /15. Your address just returns the CAIS block, indicating that there is no sub-registration. -- Bill Cole [EMAIL PROTECTED] ############################################################# This message is sent to you because you are subscribed to the mailing list <[EMAIL PROTECTED]>.
