Big 3com switches
by Dan Lockwood 12 Nov '04

12 Nov '04

Anyone out there have experience with the larger variety 3com switches (7700)? What is the general opinion on 3com in the SP space? what are the good things that they do and inevitably the bad? I'm working with a company to evaluate some of their products and wanted to get the community to weigh in as well. Off list is fine and I can summarize if there is interest. Thanks! Dan

RE: I want my own IPs
by Joe Johnson 12 Nov '04

12 Nov '04

The biggest issue has always been timing. We've caught ourselves a few times with 5 IP addresses left and had to wait to sign new customers up for a while until ARIN got back to us. Luckily, stiring up the pool of IP's usually gets a dozen or so to drop out that we missed as being available.

If you're actually _using_ the four /24s, you can demonstrate a need for a /22 today. So a good first step would be to use the four /24s until they're full. Second step would be to apply to ARIN for a /22 to replace them. Renumber into that. Then keep applying to ARIN for more space as you need it. -Bill

Re: I am new to the list and have some questions about Black Holes
by Charles Cala 12 Nov '04

Here are some links about black holes.. The interesting thing about black holes is that nothing �should� come out of them, (according to Steven Hawking) but he (hawking) later revised his theory saying something DOES make it out of the black hole, information. This I believe is where management gets their ideas from, some place where random bits of the universe got tossed, everybody thought that those things were gone for good, but no� little bits of them leaked out. http://www.damtp.cam.ac.uk/user/gr/public/bh_home.html http://archive.ncsa.uiuc.edu/Cyberia/NumRel/BlackHoles.html or perhaps you want to get info on BGP black holes http://www.google.com/search?hl=en&lr=&q=black++holes+hole+bgp&btnG=Search if I go to http://www.merit.edu/mail.archives/nanog/ and enter _ black hole _ in the little search window, I get hundreds of results, if I use _ blackhole _ I get over a thousand -charles

HOWEVER, i have two observations. #1 is that the ipv4 swamp was a huge motivator for ipv4 deployment in the early days, and its carrying costs today are still worth paying just because of the market size it helped enable. #2 is that the ipv4 swamp has stayed about the same absolute size since CIDRD was closed, and almost all growth since then has been of larger (PA) prefixes. extrapolating this for ipv6 ought to cause a number of you to go out and get ipv6 /32's today, before the swamp starts to fill up with other folks' prefixes, which will ultimately lead the members of ARIN and other RIRs to "raise the bar" for /32 allocations. and i do not expect there to be a provision for getting anything smaller than a /32 if you don't qualify for a /32. read this whole message more carefully if you are still unmotivated.

Probe dns service - anycast network
by Gere geomag 11 Nov '04

Hi, We are thinking of deploying anycast in our network for dns servers. I have the following scenario: - 10 server DNS (isc-bind) , linux and zebra for propagating ospf ip anycast. Are there someone who has developed a "solid scripts (perl/c/ecc..)" that is used to probe a dns service (udp/tcp port 53) and in case of failure (or max lookup query time problem) automatic shutdown ospf annunce or remove a server from a anycast network? Best regards Antony Findanno
