Does anyone have any leads on any job posting web sites, or leads or resumes on managers of data centers in London, England. We are currently staffing our offices there. Requires significant data storage expertise. (see backup.com and swapdrive.com) thanks Joe Grajewski

Researchers Chart Internet's 'Black Holes'
by Hank Nussbacher 07 Jun '07

07 Jun '07

http://www.wired.com/science/discoveries/news/2007/06/hubble "Despite its robust appearance, more than 10 percent of the internet flickers out like a candle every day, according to researchers who unveiled on Wednesday an experimental tool that probes the network's dark places. Ethan Katz-Bassett, a computer science Ph.D. candidate from the University of Washington introduced Hubble -- a network of deep cyberspace probes scattered around the internet - at the meeting of the North American Network Operator's Group in Bellevue, Washington. For two weeks Hubble queried a sample of 1,500 internet prefixes (a small subsection of the net) every 15 minutes. In the end it found that 10 percent of those prefixes couldn't be reached from certain corners of the internet." -Hank

True, diy PI (mmm, PI) is a major reason people use it for v4 and why they'll want something similar for v6. No internal renumbering, ever. I can see why they choose it, even with the disadvantages PI for everyone? brandon

What about managing NAT is allegedly difficult. Are you unable to easily map public addresses with private addresses on your own networks? >Stateful inspection provides security benefits. Neither SI nor NAT provides any security. It is the rules commonly implemented on top of them that can provide security. Please be consistent in the use of these terms to avoid confusing the issue.

The security comes from SI and > dropping packets that don't have an active session established > from inside, or related. Crux of the thread for sure. In an academic context NAT only swaps header addresses, however, in the world of network operators and end-users all NAT devices do SI and filtering. It is the filtering, blocking connections initiated from public addresses, that provides "NAT security". That is still "NAT security" if only because it is characteristic of virtually all NAT devices, and not the default or even a common configuration of non-NAT network devices and applications. Perhaps it is difficult to understand this vernacular "NAT" after studying Comer, Stevens et al, but when you've run the equivalent of 'sh conn' regularly for several years the narrow, some would say ivory tower, definition of NAT tends to morph into one based on actual implementations. Since this mailing list is by and for network operators as opposed to academics perhaps we could ask the later (NANAGs?) to use footnotes(1) to clarify their meaning? -- Roger Marquis Roble Systems Consulting http://www.roble.com/

Cool IPv6 Stuff
by Jeroen Massar 06 Jun '07

06 Jun '07

Hi, As more and more cool IPv6 applications and services are becoming available, I converted the former FAQ entry we had on this into a more easily found/remembered page. The page is at: http://www.sixxs.net/misc/coolstuff/ I am spamming this to NANOG, as there is bound to be ISP's out there and other service providers who might have something cool to add to that list. In case you do have some, don't hesitate to spam me back with them and I'll add them to the list so that everybody can enjoy them. As a current special, for the folks who are politically inclined, you might be interested in the G8, try: vlc http://g8tv.etherkiller.de:8000/g8-tv.ogg For a nice TV stream of the event.

It's the path of least resistance to profit. (A lot of mainstream vendors have helped push the idea that NAT is synonymous with firewalling. Take the Cisco PIX as an example, where up until very recently you had to configure NAT to allow traffic through the device.) Even people I have spoken that understand the difference between firewalling/reachability and NATing are still in favour of NAT. The argument basically goes "Yes, I understand that have a public address does not neccessarily mean being publically reachable. But having a private address means that [inbound] public reachability is simply not possible without explicit configuration to enable it". i.e. NAT is seen as a extra layer of security. I want NAT to die but I think it won't. S

Yahoo! clue
by Simon Waters 05 Jun '07

05 Jun '07

Is there a Yahoo! abuse contact around who will talk, and not just sended me canned responses? Their abuse team seems very responsive, but I fear they don't actually read the whole email, but just hit the button for the most appropriate "canned response" as soon as they think they know what is being said. (Let he who is without sin here, cast the first stone). Thanks, Simon
