Introduction• The theme is “IPv6-only”, so that’s mostly what I’ll cover
• I’ll briefly touch on:- RIPE Atlas: the platform
- RIPE Atlas: measurements
- the k-root

RIPE Atlas• A distributed network measurement platform
- You should totally participate: https://atlas.ripe.net/get-involved/become-a-host/
- You can now install and run software probes:https://atlas.ripe.net/docs/software-probe/

RIPE Atlas: What are we (you) measuring?
• How many measurements do we run?
• What is our network coverage?- How many targets (ping/traceroute)?
- How many responses?
- From which prefixes/ASNs?

RIPE Atlas: What are we (you) measuring?
• So we’re measuring responses from- around 35% of the BGP announcements
- around 50% of the ASNs originating or propagating IPv6 space
• IPv6 topology discovery is an active research area!

The k-root• We operate the DNS K-root servers
- https://www.ripe.net/analyse/dns/k-root
• DNS traffic is not HTTP traffic!

Summary• We have pretty good coverage
- ~38% of RIPE Atlas probes have IPv6 connectivity
- We run a lot of IPv6 measurements continuously
- We collect network measurements from ~50% of ASNs
- ~17% of requests to k-root arrive over v6
• Can we nudge things upwards?- Check your networks and fill in gaps in RIPE Atlas!
