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

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
