NANOG Meeting Presentation Abstract

DNS Anycast Stability
Meeting:	NANOG34
Date / Time:	2005-05-16 2:00pm - 2:30pm
Room:	Grand Ballroom II-III<BR>Grand Level
Presenters:	Speakers: Daniel Karrenberg, RIPE NCC Daniel Karrenberg is one of the founders of RIPE and led the establishment of the RIPE NCC, the first of the RIRs; before that he helped to establish EUnet, the first pan-European ISP. Daniel currently serves the RIPE NCC as Chief Scientist; his interests include Internet measurements, the development of the DNS, routing security and the evoloution of what others often call \"Internet Governance\".
Abstract:	Intuitively prefixes announced at multiple locations in the BGP topology will have more potential paths than those announced conventionally. Again intuitively this would amplify instabilities inherent in BGP routing as used in the Internet today. The presentation combines measurements of anycasted DNS root service with observations of BGP routing to document the status quo and ask more questions.
