RIPE Atlas numbers
• 9,300+ probes connected (200+ anchors)• 3,900+ results collected per second• 35,000+ user-defined measurements weekly
- Six types of user-defined measurements available to probe hosts and RIPE NCC members: ping, traceroute, DNS, SSL, NTP, HTTP (WiFi coming…)

RIPE Atlas IXP Country Jedi
• Do paths between ASes stay in country?
• Any difference between IPv4 and IPv6?
• How many paths go via local IXP?
• Could adding peers improve reachability?
• Experimental tool - Feature requests welcome!
- Depends on probe distribution in country
Massimo Candela | TOP-IX | 30 June 2016 11
Methodology
• Trace route mesh between RIPE Atlas probes
• Identifying ASNs in country using RIPEstat - Using a maximum of two probes per AS
• Identifying IXP and IXP LANs in PeeringDB

Which paths go via TOP-IX in Turin?
• Methodology:
- Only TOP-IX peering lans
- Probes 50km from centre of Turin
- Two probes for each AS
- “Outgoing paths” means out of Italy
