That depends on your corporate needs for power, security, remote hands, etc. The extended services found at Equinix & PAIX are very important for many networks. -ren At 08:00 AM 5/17/2002 -0400, Ralph Doncaster wrote: >What about NYIIX/6IIX? >Being in Telehouse where there are no monthly fees for for cross-connects >gives it a financial advantage over Equinix. > >Ralph Doncaster >principal, IStop.com >div. of Doncaster Consulting Inc. > >On Fri, 17 May 2002, ren wrote: > > > > > Hi Iljitsch, > > > > I would not consider Sprint NAP, a place closed to new customers for > > several years, an important interconnect location in the US.

Routes down to yahoo.com, etc. from Wash DC?
by Mary Grace 20 May '02

20 May '02

IS it just us out hereon the Right Coast in the Washington DC area, but are a number of routes to the Bay Area and Southern California down? We can't get traceroutes through or customer connections to www.yahoo.com, while other like www.msn.com and http://home.netscape.com come in just fine. Is it www.yahoo.com, maybe? Just wondering, as I narrowly veer close to the edge of being on-topic..... :-) Mary Grace

Interconnects
by Iljitsch van Beijnum 20 May '02

20 May '02

A bunch of us are thinking about multihoming solutions for IPv6. For this purpose, it is useful to know a bit more about how actual networks (rather than the ones existing only as ASCII drawings) interconnect. So: - What are the 12 - 18 most important interconnect locations in the world? MAE East, the Ameritech, Sprint and PacBell NAPs, PAIX, LINX and AMS-IX come to mind, but from where I'm sitting it's hard to judge whether others are important or marginal. - To how many of them do typical tier-1 and tier-2 networks connect? - Using private or public interconnects?

I was wondering if there was any online / hardcopy information about multilink frame relay that you have found useful. I was also wondering if there was any online / hardcopy information comparing multilink frame relay to standard frame relay that you have found useful as well. replies appreciated _________________________________________________________________ Send and receive Hotmail on your mobile device: http://mobile.msn.com

route statistics
by Ralph Doncaster 20 May '02

20 May '02

I'm trying to collect statistics on how many routes match certain patterns. So far I've been using zebra, set term len 0, and then sh ip bgp regexp, and wait for the total prefixes count at the end of the list. I figure there must be a better way than this, but so far haven't found one. Any ideas? Ralph Doncaster principal, IStop.com div. of Doncaster Consulting Inc.

Not that this neverending thread hasn't been an absolute blast, but I was thinking maybe if I pointed out that this has been and is already being done by several commercial and non-commercial groups, we could put an end to the "landmine" discussion? For example, see, http://isc.incidents.org/top10.html For a list of naughty hosts and nets. And there are any number of commerical solutions. For example, I believe SecurityFocus's ARIS does this kind of thing, http://www.securityfocus.com/corporate/products/tmsFAQ.shtml Pretty much all of the big IS security companies do. NIDS data from various sites is shipped off to a central database where the data is crunched, and then the distilled information is pushed back out. Pretty much the same concept? -- Crist J.

Before choosing an onling bank, I portscanned the networks of the banks I was considering. It was the only way I could find to get a rough assessment of their network security, which was important to me as a customer for obvious reasons. I'm not sure if I would have been impressed or annoyed if they had stopped accepting packets from my machine during the scan. :-) -----ScottG.
