  4. Reverse DNS • First anycast instance operational at AMS-IX • ASN 197000 • Serves in-addr.arpa, ip6.arpa and all of the RIPE NCC’s forward and reverse zones • Second anycast instance to go live at LINX in December 2010

  5. Provisioning System • New software in December 2010 • Depends on RIPE Database WG action #59.1 • Upcoming features: • Co-ordination with other RIRs for glue and DS records for ERX address space • Support for range notation (x-y.b.a.in-addr.arpa) • Support for RFC 2317 delegation • Improvements to delegation checker

  6. DNSSEC • Secure64 signers in production since June 2010 • FIPS 140-2 level 2 certified • Updated DNSSEC Policy and Practice Statement (DPS) • http://www.ripe.net/rs/reverse/dnssec/dps.html • First KSK roll-over in September had issues • Signatures with an inception date of 1 January 1970 due to a software bug • KSK roll-over was delayed until October

  7. DNSSEC in Reverse DNS

  8. K-root • Operations stable with 18 instances

  9. 2001:7fd::1

  10. K-root with DNSSEC • Outbound traffic up by 30% • Current outbound bandwidth is 80 Mbit/s with peaks up to 120 Mbit/s • No significant TCP traffic

  11. K-root and TCP

  12. Future Plans • Continuous pcap data collection from all K-root instances • Analyse data on Hadoop-based clusters • New K-root local instances • Cape Town (together with AfriNIC), Kiev • Global nodes • Expand footprint to cover under-represented regions • Trying to determine suitable locations
