Peering Traffic Volume
by Ravi Ramaswamy 25 Mar '11

25 Mar '11

Hi All - I am new to this mailer. Hopefully my question is posed to the correct list. I am using 2.5 Tbps as the peak volume of peering traffic over all peering points for a Tier 1 ISP, for some modeling purposes. Is that a reasonable estimate? Thanks Ravi

paypal and ipv6

seems that ipv4 addresses are mandatory with paypal with a stingy 15 char limit so you can't even sneak a v6 address in. we've got a long way to go. https://cms.paypal.com/us/cgi-bin/?cmd=_render-content&content_ID=developer… <https://cms.paypal.com/us/cgi-bin/?cmd=_render-content&content_ID=developer…> Mike

Question about AS Origin changes
by Yaoqing(Joey) Liu 25 Mar '11

25 Mar '11

Hi NANOG list, I am wondering if anyone can give me possible reasons for some uncommon BGP origin change activity. What we see is that sometimes the origin for a prefix seems to change from a customer AS to it upstream provider and back. In many instances the prefix simply switches back and forth for hours or even days and sometimes very rapidly . Below I’m including an example of some of the activities I see. Prefix 202.83.96/20 on border router 154.11.98.225(AS 852) At 14:10:56 Dec 04 2010, the BGP path with AS18106 as the origin At 14:11:57, the BGP path with AS9255 as the origin At 14:14:27, the BGP path with AS18106 as the origin. Thanks, Yaoqing

Google Geolocation
by Nathan Eisenberg 25 Mar '11

25 Mar '11

Would someone from Google please contact me offlist? You're geolocating some of $DAYJOB's IP space to the Netherlands, and I'm not sure how to fix it. Sadly, very few of my $DAYJOB's customers in Seattle are fluent in Dutch. (If there's an obvious form somewhere to fix this, and I missed it, then I apologize for the useless post!) Nathan

RE: Nortel, in bankruptcy, sells IPv4 address block for $7.5 million
by Jamie Bowden 25 Mar '11

25 Mar '11

Does anyone really believe MS is this naïve? I have no doubt at all that some small bit of Nortel will be transferred to MS if that's what's required for the IPs in question to be moved in accordance with normal standards, practice, and policy. Jamie -----Original Message----- From: Matthew Kaufman [mailto:matthew@matthew.at] Sent: Thursday, March 24, 2011 11:07 PM To: Jimmy Hess Cc: John Curran; NANOG list Subject: Re: Nortel, in bankruptcy, sells IPv4 address block for $7.5 million On 3/24/2011 7:59 PM, Jimmy Hess wrote: > > Because that's what IP addresses are. Totally worthless unless community > participants voluntarily route traffic for those IPs to the assignee. Note that community participants can do this with or without ARIN having updated some entries in a database. Would de-peer with Microsoft (or turn down a transit contract from them) just because they wanted to announce some Nortel address space? Would ARIN really erase the Nortel entry and move these addresses to the free pool if Microsoft doesn't play along with one of the transfer policies? Would you announce addresses someone had just obtained from ARIN that were already being announced by Microsoft? Matthew Kaufman

IN-ADDR.ARPA Nameserver Change Complete
by Joe Abley 24 Mar '11

24 Mar '11

IN-ADDR.ARPA NAMESERVER CHANGE COMPLETE This is a courtesy notification of the completion of a change to the nameserver set for the IN-ADDR.ARPA zone. There is no expected impact on the functional operation of the DNS due to this change. There are no actions required by DNS server operators or end users. For more information about this work, please see <http://in-addr-transition.icann.org/>. DETAIL The IN-ADDR.ARPA zone is used to provide reverse mapping (number to name) for IPv4. The servers which now provide authoritative DNS service for the IN-ADDR.ARPA zone are as follows: A.IN-ADDR-SERVERS.ARPA (operated by ARIN) B.IN-ADDR-SERVERS.ARPA (operated by ICANN) C.IN-ADDR-SERVERS.ARPA (operated by AfriNIC) D.IN-ADDR-SERVERS.ARPA (operated by LACNIC) E.IN-ADDR-SERVERS.ARPA (operated by APNIC) F.IN-ADDR-SERVERS.ARPA (operated by RIPE NCC) All root servers dropped the IN-ADDR.ARPA zone according to the schedule posted earlier, and all root servers now respond to queries under IN-ADDR.ARPA with an appropriate referral. Note that as part of this transition, the IN-ADDR.ARPA zone is now signed with DNSSEC and a complete chain of trust now exists from the root zone to the IN-ADDR.ARPA zone. IP6.ARPA, the corresponnding zone for IPv6 reverse mapping, was signed similarly some time ago. Regards, Joe Abley Director DNS Operations ICANN
