ARIN recognizes Interop for return of more than 99% of 45/8 address block
by John Curran 06 Dec '10

06 Dec '10

FYI, /John ---- https://www.arin.net/announcements/2010/20101020.html Posted: Wednesday, 20 October 2010 ARIN today recognizes Interop, an organization with a long-standing presence in the Internet industry, for returning its unneeded Internet Protocol version 4 (IPv4) address space. Interop was originally allocated a /8 before ARIN's existence and the availability of smaller-sized address blocks. The organization recently realized it was only using a small portion of its address block and that returning the remainder to ARIN would be for the greater good of the Internet community. ARIN will accept the returned space and not reissue it for a short period, per existing operational procedure. After the hold period, ARIN will follow global policy at that time and return it to the global free pool or distribute the space to those organizations in the ARIN region with documented need, as appropriate. With less than 5% of the IPv4 address space left in the global free pool, ARIN warns that Interop's return will not significantly extend the life of IPv4. ARIN continues to emphasize the need for all Internet stakeholders to adopt the next generation of Internet Protocol, IPv6.

Network management software with high detailed traffic report
by Sergey Voropaev 05 Dec '10

05 Dec '10

Does any one know the NMS (network management software) which can do the fallowing: 1. Monitor on Cisco Routers/Switches interface utilization every 5-10 seconds and send e-mail alarm when utilization low or high of predefined thresholds. 2. Collect net-flow statistics (at least src/dst) with granularity of 5-10- seconds. The main idea is to have detailed monitoring of the external links and to be able to know why (by what traffic type) and when link was highly utilized. Existing flow-collector can store netflow reports only with 1 minute granularity but we need 5-10 second. As about e-mail alarms - now I do it by embedded event manager on the router. But I think it would be better to use external SNMP software for that. As about detailed to 5-10 second netflow statistics there are 2 ways. 1st - Use port mirror and use some software which can analyze captured traffic and made a good reports. Do you know such software? 2nd - Use SNMP or telnet/ssh for access to the router/switch every 5-10 seconds and catch netflow counters. Do you now such software? thanks in advance for you help.

Blocking International DNS
by Marshall Eubanks 03 Dec '10

03 Dec '10

It seems that the Combating Online Infringement and Counterfeits Act (COICA) passed through the Senate Judiciary Committee with a unanimous (!) vote : http://arstechnica.com/tech-policy/news/2010/11/pirate-slaying-censorship-b… http://www.govtrack.us/congress/billtext.xpd?bill=s111-3804 I claim operational content for this as, on the basis of court orders, i..e. a "temporary restraining order, a preliminary injunction, or an injunction against the domain name used by an Internet site dedicated to infringing activities" it requires that, for foreign domain names, "(i) a service provider, as that term is defined in section 512(k)(1) of title 17, United States Code, or other operator of a domain name system server shall take reasonable steps that will prevent a domain name from resolving to that domain name’s Internet protocol address;" This expedited DNS cutoff is only available for copyright violations, not for other illegalities. Whether this has any chance of actually passing through this Lame Duck Congress remains to be seen, but my personal reading is that that is not likely. Regards Marshall

Level 3 Communications Issues Statement Concerning Comcast's Actions
by Patrick W. Gilmore 03 Dec '10

03 Dec '10

<http://www.marketwatch.com/story/level-3-communications-issues-statement-co…> I understand that politics is off-topic, but this policy affects operational aspects of the 'Net. Just to be clear, L3 is saying content providers should not have to pay to deliver content to broadband providers who have their own product which has content as well. I am certain all the content providers on this list are happy to hear L3's change of heart and will be applying for settlement free peering tomorrow. (L3 wouldn't want other providers to claim the Vyvx or CDN or other content services provided by L3 are competing and L3 is putting up a "toll booth" on the Internet, would they?) -- TTFN, patrick

FUD: 15% of world's internet traffic hijacked
by Bob Poortinga 02 Dec '10

02 Dec '10

This is starting to be picked up by mainstream media, but was was first reported here (I believe): <http://www.nationaldefensemagazine.org/blog/Lists/Posts/Post.aspx?ID=249> "Cyber Experts Have Proof That China Has Hijacked U.S.-Based Internet Traffic" "For 18 minutes in April, China.s state-controlled telecommunications company hijacked 15 percent of the world.s Internet traffic, including data from U.S. military, civilian organizations and those of other U.S. allies." This article, which quotes Dmitri Alperovitch of McAfee, is full of false data as far as I can tell. I assert that much less than 15%, probably on the order of 1% to 2% (much less in the US) was actually diverted. The correct statement is that 15% of the world's network prefixes were "hijacked", but the impact was minimal in the US. My concern is that this "report" will be presented to the US Congress without being refuted by experts in the know. My request is that someone with some gravitas please issue a press release setting the facts straight on this matter. I have been in contact with Dan Goodin at The Register but I'm just a lowly grunt with a small network. -- Bob Poortinga K9SQL <http://www.linkedin.com/in/bobpoortinga> Bloomington, Indiana US "the Internet interprets spam as noise and suppresses it"

RINA - scott whaps at the nanog hornets nest :-)
by Scott Weeks 02 Dec '10

02 Dec '10

It's really quiet in here. So, for some Friday fun let me whap at the hornets nest and see what happens... >;-) http://www.ionary.com/PSOC-MovingBeyondTCP.pdf -------------------------------------------------------------- "NAT is your friend" "IP doesn’t handle addressing or multi-homing well at all" "The IETF’s proposed solution to the multihoming problem is called LISP, for Locator/Identifier Separation Protocol. This is already running into scaling problems, and even when it works, it has a failover time on the order of thirty seconds." "TCP and IP were split the wrong way" "IP lacks an addressing architecture" "Packet switching was designed to complement, not replace, the telephone network. IP was not optimized to support streaming media, such as voice, audio broadcasting, and video; it was designed to not be the telephone network." -------------------------------------------------------------- And so, "...the first principle of our proposed new network architecture: Layers are recursive." I can hear the angry hornets buzzing already. :-) scott

I adjusted our routing to depreference TWT for reaching AS7922...which is kind of funny because Comcast clearly doesn't seem to want traffic via the route we're now sending it. 3356 7922 7922 7922 Don't want traffic via Level3...but can't take it via TWT?..I'll send it to you over Level3. At least that path works. ---------------------------------------------------------------------- Jon Lewis, MCP :) | I route Senior Network Engineer | therefore you are Atlantic Net | _________ http://www.lewis.org/~jlewis/pgp for PGP public key_________
