PCH survey on peering

by Bill Woodcock

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Howdy. We're conducting a statistical overview of peering sessions for a research paper. The paper we produce will be input into OECD guidelines on national communications regulatory frameworks, so we'd very much like it to accurately reflect the diversity of peering agreements out there in the world. At the same time, if we ask for too much data, people will be reluctant to answer our questions, so we've tried to keep the data we're collecting as simple as possible. Specifically, for each other Autonomous System you peer with, we'd be interested in knowing the following five pieces of information: Your ASN Your peer's ASN Whether a written and signed peering agreement exists (the alternative being that it's less formal, like a "handshake agreement") Whether the terms are roughly symmetric (the alternative being that it describes an agreement with different terms for each of the two parties, like one paying the other, or one receiving more or fewer than full customer routes) If a jurisdiction of governing law is defined The easiest way for us to take the information is as a tab-text file or spreadsheet, consisting of rows as follows: Your ASN: Integer Peer ASN: Integer Written agreement: Boolean Symmetric: Boolean Governing Law: ISO 3166 two-digit country-code, or empty For instance: 42 <tab> 715 <tab> false <tab> true <tab> us <cr> 42 <tab> 3856 <tab> true <tab> true <tab> us <cr> The ASNs are just there so we can avoid double-counting a single pair of peers, when we hear from both of them. As soon as we've collated the data, we'll strip the ASNs to protect privacy, and only the final aggregate statistics will be published in any case. We've currently got about 10,000 sessions documented, and would love to have as many more as possible. We'd like to finish collecting data by the end of the second week of April, two weeks from now. If you're able to help us, please email me the data in whatever form you can. If you need a non-disclosure, we're happy to sign one. Thanks for considering this, -Bill Woodcock Research Director Packet Clearing House -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.11 (Darwin) iEYEARECAAYFAk2UqpYACgkQGvQy4xTRsBGvowCgzXIkFOEfqj9BCgGkqhiv8AgF xGwAoLl69OQ8giYmnT6S7zwLBBu7XeYZ =D38f -----END PGP SIGNATURE-----

Achtung: moegliche (Mail) Probleme durch Aenderung der Nameserver fuer .in-addr.arpa !

by swinog-list＠dudes.ch

Vor einiger Zeit ging ja eine Mail herum, dass die globalen Nameserver fuer .in-addr.arpa aendern werden, dass dies aber keine Auswirkungen auf den taeglichen Betrieb haben wuerde. Nun, es hatte... Wer auf seinen Nameservern bislang den folgenden Code drin hatte, um reverse Lookups zu beschleunigen, kann seit der Umstellung keine reverse Lookups mehr ausfuehren: zone "." { type slave; file "slave/root.slave"; masters { 192.5.5.241; // F.ROOT-SERVERS.NET. }; notify no; }; zone "arpa" { type slave; file "slave/arpa.slave"; masters { 192.5.5.241; // F.ROOT-SERVERS.NET. }; notify no; }; zone "in-addr.arpa" { type slave; file "slave/in-addr.arpa.slave"; masters { 192.5.5.241; // F.ROOT-SERVERS.NET. }; notify no; }; Dieser Bereich ist standardmaessig auf aktuellen FreeBSD Servern auskommentiert, es wird in einem Kommentar aber empfohlen, ihn fuer Nameservern mit hohem Verkehrsaufkommen zu aktivieren. Nach der Umstellung der in-addr.arpa Zonen funktioniert das Slaving _NICHT_ mehr, auch nicht von den neuen Servern. Resultat: Reverse-Lookup funktioniert nicht mehr. Wer Mailserver betreibt, die auf einem gueltigen Reverse-Lookup bestehen fuer eine einkommende Verbindung, wird ohne Anpassung seiner Nameserver nun beginnen (je mehr gecachte Zonen expiren desto mehr) einkommende Verbindungen abzuweisen, und dieses Abweisen wird zumindest bei unserm Setup mit "Relaying temporarily denied. Cannot resolve PTR record for x.x.x.x" begruendet. Eventuell sind die vor kurzem beschriebenen Probleme, dass bluewin seine eigenen Adressen nicht akzeptiert (mit "relay denied") auf das gleiche Problem zurueckzufuehren... LG, Markus

Connectivity problems with .255 IP Adress

by Mike Kellenberger

Hi One of our customers got a .255 IPv4 address assigned by sunrise. I know that this can be a valid host address with a netmask of /23 or greater, but the strange thing is, that he can't reach any of our Windows Server 2003 hosts with this IP. Windows Server 2008 Servers in the same subnet are no problem... Does anybody know of such a problem? Mr. Google couldn't give me any satisfactory results... :-) Cheers, Mike -- Mike Kellenberger | Escapenet GmbH www.escapenet.ch +41 52 235 0700/04 Skype mikek70atwork

IN-ADDR.ARPA Nameserver Change Complete

by Joe Abley

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
