Transcript of "32-bit ASN for DNS Services"

  1. 1. RIPE Network Coordination Centre 32-bit ASN for DNS Services Anand Buddhdev DNS Services Manager, RIPE NCC Anand Buddhdev RIPE 60, May 2010 http://www.ripe.net 1
  2. 2. RIPE Network Coordination Centre Background • RIPE NCC managed zones - Forward zones (ripe.net, etc) - Reverse zones (IPv4 and IPv6) - ENUM (e164.arpa) - Secondary for ip6.arpa and many other zones • Two servers - ns-pri.ripe.net - ns-sec.ripe.net • Single servers • Unicast Anand Buddhdev RIPE 60, May 2010 http://www.ripe.net 2
  3. 3. RIPE Network Coordination Centre Upcoming Changes • Multi-server architecture • Anycast - 193.0.9.0/24 - 2001:67c:e0::/48 • Serve in-addr.arpa • Independent ASN Anand Buddhdev RIPE 60, May 2010 http://www.ripe.net 3
  4. 4. RIPE Network Coordination Centre ASN 197000 Anand Buddhdev RIPE 60, May 2010 http://www.ripe.net 4
  5. 5. RIPE Network Coordination Centre Interoperability • Older BGP speakers talk to AS 23456 • Transitive attribute AS4_PATH contains the 32-bit ASN • 32-bit ASN speakers reconstruct the correct path • All major vendors have 32-bit ASN support Anand Buddhdev RIPE 60, May 2010 http://www.ripe.net 5
  6. 6. RIPE Network Coordination Centre Connection Details • Connection at Amsterdam Internet Exchange • 6 transit providers - All support 32-bit ASNs • Peering with AMS-IX route servers - Recent OpenBGPD - Also supports 32-bit ASNs - 111 of 333 peers have 32-bit ASN support Anand Buddhdev RIPE 60, May 2010 http://www.ripe.net 6
