Hi. I'm by no means an ip/networking expert, and we're having some difficulty communicating with the boffins at AT&T. Any input/advice/translation would be appreciated.
We own our own class C netblock. Our previous provider, Sprint, had no problem "adding" it to their network/advertising it (that circuit is now disconnected). We've started using an AT&T colo facility, and we're having a lot of trouble trying to get AT&T to do the same thing there that Sprint was able to do for us. AT&T is refusing to advertise our netblock/path it to our cabinet unless we have an AS number. ARIN has refused to give us one on the grounds (rightly so) that we're not multi-homed.
muli-homing is one way to justify an ASN, "unique routing policy" is the other. Your directly assigned /24 could be a reason to have a unique routing policy, especially if your upstreams are unwilling to originate it from their ASN(s). You may want to re-apply for an ASN and explain that you will be announcing your directly assigned block in section 14 of the template. - Kevin
