3. • Measurement
Passive: collect data as is happens
Active: Create an experiment to measure
• Metrics

4. Data collected by NZRS
Explore some of our metrics, passive and active

5. • DNS queries for 4/7 nameservers for .nz
Large dataset, almost 3 years
Includes AAAA queries
Signals hosts interested in IPv6 addresses
Includes IPv6 sourced queries
Signal DNS clients with IPv6 connectivity
• .nz Zone Scans
Started in August 2013
Number of domains with services publishing IPv6
addresses
IPv6 .nz DNS Data
Feb 2016IPv6 measurement for NZ 5

6. • Traffic for 4 out of
7 nameservers
• All based in NZ
• ns1/ns2 with IPv6
addresses
• Smoothed curve
• Daily patterns
• Spikes due to
unusual activity
.nz DNS queries

7. • Closer look ofIPv6
traffic
• There is some
growth, but slower
than IPv4 traffic
.nz IPv6 DNS Queries
Feb 2016IPv6 measurement for NZ 7

8. • Compare A
queries (IPv4)
against AAAA
(IPv6)
• The rest of the
traffic is not
included
• Better growth,
closer gap
• OS software
updates adding
IPv6 support
Counting per query type

14. • Using RIPE data
• Ratio of # routable
IPv6 over #
routable IPv4
prefixes
• IPv6 growing
faster than IPv4
• But still quite slow
