Changing ASNs - Gotchas??
by Flint Barber 28 Oct '05

28 Oct '05

ASN - Migration What are the real gotchas for changing ASNs that people have run into? There is a minor one in terms of route-registry timeliness, I can't update RADB until the change takes place and ISPs don't run their update scripts on my timetable. So I see there might be a gap. If someone knows a strategy there, I would be most appreciative. Beyond that, what extended trouble have engineers seen from remote networks? As background, I am changing an ASN at one location that has 5 ISP peers( all ranked in the top 20) connected to it over the weekend. I have made all of the arrangements with those ISPs the best I can, but am concerned some about propagation beyond them. The ASN was assigned about 60 days ago by ARIN and I have added it to RADB so most filters should have been updated. Anyone know of trouble beyond what I have mentioned or have a strategy to ensure a successful migration to mitigate the gotchas?? -Flint

I've found from experience that connectivity to various .mil sites varies on a moment to moment basis based on your source address and the mood of the day. That being said, the best luck I've had getting issues resolved is by contacting DISA, by phone, and opening a case - http://www.disa.mil/main/support/gnosc_rnosc.html Usually wound up with someone stateside in Columbus (be VERY patient). Hope this helps and good luck! -----Original Message----- From: owner-nanog(a)merit.edu [mailto:owner-nanog@merit.edu] On Behalf Of Gregory Hicks Sent: Friday, October 28, 2005 8:34 AM To: Curtis(a)greenkey.net; ops.lists(a)gmail.com Cc: nanog(a)merit.edu Subject: Re: fleet.navy.mil DNS / network ops contact please > Date: Fri, 28 Oct 2005 10:36:22 +0530 > From: Suresh Ramasubramanian <ops.lists(a)gmail.com> > To: Curtis Doty <Curtis(a)greenkey.net> > Subject: Re: fleet.navy.mil DNS / network ops contact please > Cc: NANOG <nanog(a)merit.edu> > > > On 27/10/05, Curtis Doty <Curtis(a)greenkey.net> wrote: > > > > The information you seek is traditionally stored in the SOA record. > > > > fleet.navy.mil SOA ns1.fleet.navy.mil. prnoc.fleet.navy.mil. > > 2005090600 1800 900 3600000 1800 > > > > Why there is no @ sign is a mystert left to the reader of the RFCs > > or of the Cricket book. :-/ > > > > Traditionally, yes.

BGP Peering issues???
by Braun, Mike 28 Oct '05

28 Oct '05

Apologies for straying off topic, Years ago several tools and sites were available for troubleshooting BGP routing tables and viewing reachability over the Internet. I remember using a site that, when you provided an ASN or IP address, you received a tree-graph showing multi-hop peer points and latency statistics from dozens of sources all over the internet. I know a lot of these sites went away after the release of the vulnerability with the BGP's peering process was disclosed. Some of the sites I bookmarked advertised that they would return once a more secure way of offering this information was worked out. They eventually just went away (example being http://nitrous.digex.net) Did anything replace them? What are some of the tools and sites you use to test if you network blocks are being seen where they should be? Any suggestions would be greatly appreciated.

by Sabri Berisha 28 Oct '05

28 Oct '05

[ apologies for the wide distribution ] Dear reader, On november the 1st 2005, the rbl.cluecentral.net ip-to-country and ip-to-as DNS list will cease to exist. All queries will fail and on december the 1st 2005 I will remove the dns-servers from the machines they are running on. Important note: some users have been using this list for explicit whitelisting purposes of their own IP space. Please make absolutely sure that you have alternatives. Refer to http://moensted.dk/spam for a list of possible alternatives for your configuration. Any queries/flames/followups are welcome via private e-mail. Thanks, -- Sabri please do not throw salami pizza away
