SBC in my area (Dallas) went from wide open to outbound 25 blocked by default/opened on request. I think doing the same thing with port 22 would hardly be an undue burden on users, and would help keep botnets in check. ------------------------------------------------ Might as well do TCP 20, 21 and 23, too. Woah, that slope's getting slippery! scott

Transition Planning for IPv6 as mandated by the US Govt
by Glen Kent 19 Mar '08

19 Mar '08

Hi, I was just reading http://www.whitehouse.gov/omb/egov/b-1-information.html#IPV6, released some time back in 2005, and it seems that the US Govt. had set the target date of 30th June 2008 for all federal govt agencies to move their network backbones to IPv6. This deadline is almost here. Are we any close for this transition? I have another related question: Do all ISPs atleast support tunneling the IPv6 pkts to some end point? For example, is there a way for an IPv6 enthusiast to send his IPv6 packet from his laptop to a remote IPv6 server in the current circumstances if his ISP does not actively support native IPv6? Cheers, Glen

Operators Penalized? (was Re: Kenyan Route Hijack)
by Glen Kent 17 Mar '08

17 Mar '08

> > > > Usually unintentional. See Pakistan Telecom for recent example. > > Pakistan's blackhole was semi-unintentional, kind of like you tried to > shoot your spouse but the bullet went through the wall and > "unintentionally" hit a neighbor. Do ISPs (PTA, AboveNet, etc) that "unintentionally" hijack someone else IP address space, ever get penalized in *any* form? Depending upon whom and what they hijack, and who all get affected, it sure can get them lot of (undesired) publicity - news, articles, nanog discussions/presentations, ietf discussions, blogs - but, it doesnt really hurt them much, does it? AboveNet, unlike PTA, got a lot less publicity for their achievement, primarily because they didnt put millions off, from watching imbecilic videos of cats jumping the cars, and people slipping in snow - a simple google test corroborates this. While you get pages and pages of sites that talk about "PTA Youtube", you only get a handful when you do "Abovenet Africa Online". So, is there anything that can be done to discourage such mishaps? What do we do if an ISP, again accidentally, hijacks another address block or blackholes them? Would it pain them if their announcements were suppressed, or reachability (more specifically origination information) is damped for some time? I understand, this is opening up a pandora's box, because this ISP could be providing transit services to other ISPs, and this might inadvertently affect them. So, i am not suggesting a solution - i am seeking suggestions on what can be done about this? And before this, if there is anything that we as a community want to do about this? Affably, Glen

The results of the survey will be presented and discussed at the ARIN XXI Public Policy and Members Meeting to be held in Denver 6-9 April 2008, and the survey data will support ongoing research.
