Here are some other examples but they are at the same OID aside from the presumed peer identifier (it is not the peer router ID, I can say that much for certain - for example none of the routers below are from 174 but the one above actually is):

>From what I've read, that [32.1.5.80] is the dotted-quad version of the 
first 32-bits of the 128-bit peer IP...and the kicker is that if you have 
multiple peers in the same /32, the stats for all of them get merged 
together.  Are you peering with Cogent or a cogent customer in 
2001:550::/32 (if I did the math correctly)?

The odd thing is, that's more or less the same OID I use for v4 peer info, 
but on 12.2(33)SXI, all it shows me is the ipv4 peers.
