Status report on primary and secondary DNS load DNS Operations SIG APNIC 18 2nd September 2004, Fiji

Summary New data collection method Primary load Secondary load Conclusions Discussion

New Statistics gathering process Started May ‘04 Improved accuracy Every query/answer counted Allowing quantitative analysis Per zone inspection Query response analysis Historical data not yet imported Measures not fully compatible Does not ‘replace’ old method - augments!

Primary load Primary Servers ns1.apnic.net (AU) ns3.apnic.net (JP) ns4.apnic.net (HK) All servers authoritative for the same zones.

Primary

Primary zones secondary Zones A “good” zone 15 in-addr.arpa zones 6 ip6.arpa zones A “good” zone Low NXDOMAIN High referral

Top 5 primary zones 61.in-addr.arpa 218.in-addr.arpa 221.in-addr.arpa

Secondary load Secondary Servers sec1.apnic.net (AU) sec3.apnic.net (JP)

Secondary

Secondary zones 13 ccTLD 88 Member’s in-addr.arpa 22 in-addr.arpa from other RIRs 32 ip6.arpa zones All from RIRs

Top 5 secondary zones 200.in-addr.arpa (LACNIC) 213.in-addr.arpa (RIPE) 217.in-addr.arpa (RIPE) 81.in-addr.arpa (RIPE) 62.in-addr.arpa (RIPE)

Conclusions Capacity planning / Server load Servers running free from strain APNIC can house additional member secondary services for *.arpa Will be able to handle DNSSEC Based on measures from inter RIR co-ordination. Less than 10mb in total network traffic
