IPv6: numbering of point-to-point-links
by Lasse Jarlskov 01 Feb '11

01 Feb '11

Hi all. While reading up on IPv6, I've seen numerous places that subnets are now all /64. I have even read that subnets defined as /127 are considered harmful. However while implementing IPv6 in our network, I've encountered several of our peering partners using /127 or /126 for point-to-point links. What is the Best Current Practice for this - if there is any? Would you recommend me to use /64, /126 or /127? What are the pros and cons? -- Best regards, Lasse Jarlskov Systems architect - IP Telenor DK

Fwd: [arin-announce] ARIN Resource Certification Update
by John Curran 31 Jan '11

31 Jan '11

Copy to NANOG for those who aren't on ARIN lists but may be interested in this info. FYI. /John Begin forwarded message: From: John Curran <jcurran(a)arin.net<mailto:jcurran@arin.net>> Date: January 24, 2011 2:58:52 PM EST To: "arin-announce(a)arin.net<mailto:arin-announce@arin.net>" <arin-announce(a)arin.net<mailto:arin-announce@arin.net>> Subject: [arin-announce] ARIN Resource Certification Update ARIN continues its preparations for offering production-grade resource certification services for Internet number resources in the region. ARIN recognizes the importance of Internet number resource certification in the region as a key element of further securing Internet routing, and plans to rollout Resource Public Key Infrastructure (RPKI) at the end of the second quarter of 2011 with support for the Up/Down protocol for those ISPs who wish to certify their subdelegations via their own RPKI infrastructure. ARIN continues to evaluate offering a Hosting Resource Certification service for this purpose (as an alternative to organizations having to run their own RPKI infrastructure), but at this time it remains under active consideration and is not committed. We look forward to discussing the need for this type of service and the organization implications atour upcoming ARIN Members Meeting in April in San Juan, PR. FYI, /John John Curran President and CEO ARIN _______________________________________________ ARIN-Announce You are receiving this message because you are subscribed to the ARIN Announce Mailing List (ARIN-announce(a)arin.net<mailto:ARIN-announce@arin.net>).

Did anybody know from when or from which Service Pack was introduced SMB2 on Windows XP? The official documentation MS-SMB2 (v20101230) say SMB2 is only supported on Vista, Seven, 2008 and 2008 R2 while it seems (i may be wrong) supported on XP SP3? Thank you

Ipv6 for the content provider
by Charles N Wyble 31 Jan '11

31 Jan '11

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hello, All the recurring threads about prefix length, security posture, ddos, consumer CPE support have been somewhat interesting to my service provider alter ego. Ipv6 is definitely on folks minds this year. The threads seem a lot less trollish as well. It appears some significant progress is being made, and peoples opinions are firming up. Hopefully this will help move ipv6 adoption forward. I have recently turned up an ipv6 tunnel with he.net and have end to end connectivity. I'm using pfsense as my routing platform. It was pretty easy (about 10 minutes of total work I think). So I can connect to various ipv6 enabled sites on the interwebz. This seems to be the first step in deployment. For the most part, I'm a data center/application administrator/content provider kind of guy. As such, I want to provide all my web content over ipv6, and support ipv6 SMTP. What are folks doing in this regard? Do I just need to assign ip addresses to my servers, add AAAA records to my DNS server and that's it? I'm running PowerDNS for DNS, Apache for WWW. Postfix for SMTP. Feel free to point me at any good manuals and say RTFM :) - -- Charles N Wyble (charles(a)knownelement.com) Systems craftsman for the stars http://www.knownelement.com Mobile: 626 539 4344 Office: 310 929 8793 -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.10 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iQIcBAEBAgAGBQJNQGZvAAoJEMvvG/TyLEAt9ykP/ROLSWz3LmAF78OMBEhWEMvX MjOVR2QK6kQ3byV8WLro95tCOuyo8L8fUC60KyFh4XRsedb7xk6S8cTER80zmGzG rOAFVpNyJ1QzCcf4MYpj8xHn9zM6Fywft4VzKQEgDvlV8yD0VZKJi+fNj4noZ5oK tmM1s9Is5db3d5ldrC6M54TQJsbaZiuz+FrFtpkENraJIWlOeU3laM6kvwzvYpok BKtnaY6zBq42QovpJ+MU+lmanCB6Z0r3e2cSB+N7XJL0Va/Y2IW/eZn35S+dE3xk y7RPSZu2jDxJ6atQJVIBpjfL6oqUUr+0RHc+gX4VJyOrwpEuJQ/GvTiRDTUZkA0A twhvQnS6yc5G8L+iwID4YqkVKNCFcJUtAHUntqmy1FqTe9iQSlZdUPPhKrkRE7zW B2S2T0Lv6a/neHU5yfsGjiYbIAy7keXoiMPbR4ZJxC/KkogfWNgMZBVpjGVn0NI4 COOymyFYgvQFiXIpvmpQn0iLFcWmmGdwV2DPvxMArdmfw2SeyipJiBSeeEbb4ZG4 kw1LOrI7+OGnoDEByAtkZPh42wAbXbrSw9WeWvphAsQ2dAmASqXUKuHTDXd1laCC yi37NTRmWACNHKcVEhpk3saJDCsPPVx6ECYfhSsSALZDn6696BvFXZnN2423Fmk7 dtMKM38+rxz9r4IL5O+n =Mi6R -----END PGP SIGNATURE-----

Contact at level 3 RE IRR database?
by Andrew Alston 31 Jan '11

31 Jan '11

Hi All, I was wondering if anyone had a direct contact at level 3 who deals with their IRR database, since my queries logged with them on Saturday to both noc@ and abuse@ have gone unanswered. I have just taken a look at the following: whois -h whois.radb.net \!gAS11908 and there is a *HUGE* amount of IP space registered in the Level3 IRR database that is propagating to the other databases that clearly does not belong to AS11908. (Beyond the initial prefix of ours that noticed). Thanks Andrew Alston TENET - Chief Technology Officer Phone: +27 21 763 7181
