Routing Loop

Hello,
There is a routing loop while accesing my network 194.9.82.0/24 from
some networks on the Internet.

| This is a test done from lg.above.net looking glass.

RE: Routing Loop [In reply to]

If it continues for any length of time then contact above.net. To find their contact information, check their registrar.

e.g. whois above.net gets you

Technical Contact:
AboveNet Communications, Inc. dns[at]ABOVE.NET
AboveNet Communications, Inc.
50 W SAN FERNANDO ST STE 1010
SAN JOSE, CA 95113-2414
US
408-367-6673 fax: 408-367-6688

If that does not help, then you can solicit for better contact information (from NANOG.) I am betting above.net knows about this and is already working on it.

Good luck!

There's still a routing look at above.net, as documented by others and the
other listserv you posted this on (cisco-nsp?).

Uh, still seems to be unhappy. Have you tried poking the above.net NOC?

Re: Routing Loop [In reply to]

There's also somewhat odd data in RADB (look at the changed: line):

route: 194.9.64.0/19
descr: SES-Newskies Customer Prefix
origin: AS16422
remarks: SES-Newskies Customer Prefix
notify: noc[at]ses-newskies.com
mnt-by: MNT-NWSK
changed: noc[at]ses-newskies.com 20080314
source: ARIN

This is in the middle of RIPE-managed swamp space, a /19 definitely
doesn't belong there.

Yeah, I saw that a bit earlier and it did seem incredibly suspicious
given the timing. Had I seen anything in the routing system itself for
that explicit /19 related to this I would mentioned it, but nothing
there.

Amazingly, a query to the NOC at SES Newskies yielded a near-
immediate response, which said they added it a few days back because
they were updating some policies and noticed it existed in a prefix
list for
one of their upstreams, that it appeared to be legacy, and that they'd
get
it removed.

All the more reason RIR allocation authentication used to seed IRR
information would be of value for routing policy specification, let
alone
informational purposes.

7018 is still seeing announcements from 6461,
and the Oregon Routeviews server route-views.routeviews.org also sees
many announcements
from different ISPs seeing it announced from 6461.

The whois entry for Above.net lists the NOC as
RTechHandle: NOC41-ORG-ARIN
RTechName: AboveNet NOC
RTechPhone: +1-877-479-7378
RTechEmail: noc[at]above.net

Thanks; Bill

Note that this isn't my regular email account - It's still experimental so far.
And Google probably logs and indexes everything you send it.
