Summary Reports

Notes

The I-root data from Autonomica has anonymized source IP addresses due to privacy regulations within the country of that data's origin. For k.root, RIPE NCC’s contribution to DITL 2015 is comprised of the following datasets: - k.root-servers.net, available in files under *.k.ripe.net - AS112 pcaps, available in files under ns1.ams.as112.ripe.net - f.in-addr-servers.arpa. and f.ip6-servers.arpa., available in files under *.authdns.ripe.net The following data is missing: - k1.ams-ix.k.ripe.net was down during the DITL 2015 collection window - ns1.del.k.ripe.net was down due to a power outage from 20150413T090359Z to 20150414T055425Z - ns[123].lcy.authdns.ripe.net were not collecting due to storage constraints - k1.ficix.k.ripe.net from 20140413T1100Z to 20140413T1459Z due to human error The B-root data's source IPs are anonymized (last 8 bits for IPv4 and last 32 bits for IPv6).

Access To Data

DNS-OARC members can access DITL data on the DNS-OARC analysis servers. Please contact the DNS-OARC Admin for more information.
