Hi all, Nevil Brownlee is graciously considering this document for the independent-submission stream:
http://tools.ietf.org/html/draft-jabley-dnsop-anycast-mapping-02 It's an informational document that describes the various mechanisms provided at L-Root to identify what anycast node you see from your special place in the network. The goals are (a) publication of details about a particular Internet infrastructure service (L-Root), and (b) providing a worked example that might serve as useful input to design exercises carried out by other people with anycast DNS infrastructure. Nevil needs some additional reviews before he can make progress. There's only about 8 pages of text here (many of which are filled with example output from dig, etc). If you have a spare 10 minutes to be able to give your impressions, it would be appreciated. Please send reviews to Nevil at [email protected], ideally cc'ing me so I can know when to stop asking people for reviews. :-) Joe > A Summary of Various Mechanisms Deployed at L-Root for the > Identification of Anycast Nodes > draft-jabley-dnsop-anycast-mapping-02 > > > Abstract > > Anycast is a deployment technique commonly employed for > authoritative-only servers in the Domain Name System (DNS).
