RE: Peering point speed publicly available?

Not to mention I have run across a few providers who skew their dns records to make their network look bigger/faster.

Like I said it might get you a vague idea, but I wouldn’t place money on it. Just like GE might really be 10GE and FE 
might only be limited to 10Mbps.

How often do you think IP's get moved around, and the DNS doesn't?

Sometimes it can give a hint. However, if the ISPs are following the
³interface name² convention, you¹ll get something like P3-1-2, which just
tells you its Packet Over SONET. That can mean anything from OC-3 to OC-192.
³ge² could mean 10 gige :)

The "2488M" from glbx is nice, but not too common.

It would be so nice if this were standardized between all providers. But
naming conventions are really political - they sometimes provoke huge fights
even within providers.

However MPLS hidden hops may hide internal paths, and any connection may be
limited to slower than its line rate, and dns entries may be old....
 
It's not publicly available at one source that I'm aware of, and if there is
they don't have my info.

Subject: Peering point speed publicly available?

NANOG,
 
I have a question regarding information on my ISP¹s peering relationships.
Are the speeds of some or all peering relationships public knowledge, and if
so, where can I find this?  By speed, I mean bandwidth (DS3, OC3, 100Mbps,
1Gbps, etc.).  I am trying to transfer large stuff from my AS, through my ISP,
through another ISP, to another AS, and I¹m wondering how fast the peering
point is between the ISPs.  I¹m working with my provider to get this
information as we speak, but I¹m wondering if it¹s available publicly
anywhere.  If it were, this could be one way to evaluate providers in the
future, I guessŠ
