ok, let's suppose that usually provides the most appropriate environment for placing the dns servers and their co-infrastructure. taking it only technically, providing the connectivity for the ixp is a detail (to announce or not to announce). maybe the ixp could allocate a 'stub' subnet - separate from the transit subnet - and provide a voluntary mlpa to all the hosted isps. this would not break the isp policies on announcing the transit ixp subnet. all these are details. i see a space for another topic in this thread - updating the dns infrastrucure a bit. to be more specific: - would the ixp-located tld dns servers server only a small set of tld's each? if so, would it be region-based or agreement-based? - would it be worth the effort starting a project similar to irr that would serve as a common source for dns configurations? it'd be nice to hear your oppinions -- Tomas Daniska systems engineer Tronet Computer Networks Plynarenska 5, 829 75 Bratislava, Slovakia tel: +421 2 58224111, fax: +421 2 58224199 A transistor protected by a fast-acting fuse will protect the fuse by blowing first. > -----Original Message----- > From: Arnold Nipper [mailto:arnold@nipper.de] > Sent: 6. júna 2002 16:29 > To: Daniska Tomas > Cc: Nipper, Arnold; nanog(a)merit.edu > Subject: Re: Re: KPNQwest ns.eu.net server. > > > On Thu, Jun 06, 2002 at 04:13:08PM +0200, Daniska Tomas wrote: > > how would you guarantee connectivity? > > > > as you have a lot of ISPs around you it should be really easy > to get some > connectivity.

Are you seeing ATM framing errors at Chicago AADS?
by John Kristoff 06 Jun '02

06 Jun '02

The Chicago SBC (formerly AADS) NAP upgraded their Lucent switch code this past Sunday and we suspect we may be having some problems due to that upgrade. If anyone else is there and has been seeing framing errors since then, I'd appreciate a private reply back saying so (or not even). It would be particularly valuable to know what vendor's equipment you have on your side of that link as well. Thanks, John

how would you guarantee connectivity? should each isp present should provide bandwidth as part of collocation expenses? should the opexes be included in the colo bill? and then - this would probably make the colo becoming a connectivity provider, wouldn't it? -- Tomas Daniska systems engineer Tronet Computer Networks Plynarenska 5, 829 75 Bratislava, Slovakia tel: +421 2 58224111, fax: +421 2 58224199 A transistor protected by a fast-acting fuse will protect the fuse by blowing first. > -----Original Message----- > From: Nipper, Arnold [mailto:arnold.nipper@de-cix.net] > Sent: 6. júna 2002 16:07 > To: Jan-Ahrent Czmok; Sabine Dolderer/Denic > Cc: apnic-talk(a)lists.apnic.net; apops(a)lists.apnic.net; > ddiaz(a)ripe.net; joao(a)ripe.net; lir-wg(a)ripe.net; > nanog(a)merit.edu; randy(a)psg.com; routing-wg(a)ripe.net; tech-l(a)ams-ix.net > Subject: Re: Re: KPNQwest ns.eu.net server. > > > > As a lot of people are offering secondary services: may be > it's a good idea > to place infrastructural services at IXP.

Clarification needed on ATM
by Rich Sena 06 Jun '02

06 Jun '02

OK - sorry if this is elementary - however I am dealing with a challenge to the security of some ATM links that we have connecting remote facilities to a main campus. The connections are all PVPs with individual PVCs defined point to point. The concern that is being raised is that although these connections appear point-to-point PVCs to the router interfaces at our sites and our main campus - they are more than likely switched SVCs on the provider backbone... I had thought that a PVC was a nailed up connection between vpi-vci pairs throughout the provider ATM network - is that an incorrect assumption? And if so is the scenario that was raised possible/probable and a concern? Thanks for any info kids... -- Rich Sena - ras(a)thick.net ThickNET Consulting "On the way to understanding; you understand, and forget."

Niagara Falls cheapie trip
by Simon Lockhart 06 Jun '02

06 Jun '02

All, For those of you going to NANOG25, I'm planning on driving up from the hotel to Niagara Falls for a bit of a tourist on Saturday. A few people have expressed an interest in doing likewise. In the interests of doing a bit of co-ordination, can I suggest we meet at 10am in the hotel foyer, and head off from there. If people want to email me privately, I'll collect a list of who has got cars and who needs a lift, but I can't help resolve mismatch of numbers!

Bogon list
by Rob Thomas 06 Jun '02

06 Jun '02

Hi, folks. For a while folks have asked me to add an aggregated ACL, prefix-list, or black hole routes to the various templates on my site. I've avoided this for a variety of reasons, and decided to create the best of all worlds - the bogon list. :) This list includes the bogons, in both aggregated and non-aggregated form. The list includes bit notation, dotted decimal, and Cisco ACL styles. This is handy for blocking the bogons, egress and ingress, at your borders. Take a peek at it here: http://www.cymru.com/Documents/bogon-list.html Comments and feedback are VERY welcome! Be the first in your ASN to join the CREDITS section. :) Thanks!

| While on the subject of IXP blocks, we also ended up redistributing the | IXP blocks and sending them to our BGP customers (who do not receive a | default) so that traceroutes and such from Looking Glasses do not break. | They can then choose to filter them as they wish. This is backwards. Do not break the architecture to fix a broken looking glass (or to work around bad interpretations of real-world traceroute results). Spend a few minutes scripting your looking glass software so that if it sees a well-known target, or an expected real-world result (1918 addresses that YOU are using, with expected ttl-distance), it returns a "sanitized" result to a naive looking glass user. I wonder if there exists the possibility of a useful (perhaps open source) generalized expert system to interpret traceroute data? "configure; make; make install" is probably even easier than breaking one's filter lists to leak prefixes all over the place. Sean. (that was a hint. you know who you are.)

IP renumbering timeframe
by Ralph Doncaster 05 Jun '02

05 Jun '02

We entered into a contract with Cogent for service, and were assigned a /22 for our use. This reassignment was listed in Cogent's rwhois server (they don't SWIP). They also gave written permission to another transit provider (Peer1) to accept our BGP announcements for the /22. We have been announcing them to our Peer1 and over a dozen peers for a few months now. After paying Cogent $11K, a billing dispute developed. On Friday May 3 we terminated our service with Cogent, and on May 5 Cogent contacted our main internet connection provder to stop routing these IPs. Cogent did not contact us first. There is still an RADB entry for this block with our AS21936 as the origin. Under pressure from Cogent Peer1 complied, though I think I have them convinced that a few hours notice on a Sunday evg is not a reasonable amount of time to renumber from a /22. What is the generally accpted timeframe for renumbering? My reading of ARIN policy would seem to imply at least 30 days. Ralph Doncaster principal, IStop.com div. of Doncaster Consulting Inc.

New mailing list for Verizon DSL ISP's
by Christopher X. Candreva 05 Jun '02

05 Jun '02

Since a discussion of NAS/CAIS DSL came up last week, I am assuming there are at least some DSL resellers out there, so . . . Verizon had a converence call for the Northeast ISPs this afternoon to introduce a new product. It began with them explaining to us why our customers might want a static IP and went downhill from there. This did however get me in touch with at least one other ISP reselling Verizon DSL, and it seems we've both thought some sort of forum for Verizon reselling ISPs to ask questions and discuss issues would be helpfull. SO -- I've created a mailing list, verizonisp(a)westnet.com . To subscribe, send the single word subscribe to verizonisp-request(a)westnet.com This is intended as a forum for Verizon DSL resellers across the country to disccus an issues related to the service: Configuration, operation, trouble resolution, dealing with Verizon, etc. This is completely unofficial, not sanctioned by Verizon . ========================================================== Chris Candreva -- chris(a)westnet.com -- (914) 967-7816 WestNet Internet Services of Westchester http://www.westnet.com/
