RE Topology Report
Explore Internet2's peering topology and the routes seen across each session, refreshed daily.
LPPv2
Probe the observed routing policy for any IPv4/IPv6 address, hostname, or IPv4 prefix — no traceroutes, just the answer.
ROA Planner
Plan and validate RPKI ROAs for your prefixes.
Whois Web
Look up RIR registration and IP allocation hierarchy for any address or prefix.
IRR AS-SET Planner
Build and analyze IRR AS-SET objects for your customer cone.
Partial ASPA Planner
Suggest RPKI-ASPA providers for your Autonomous System. Doesn't yet cover every case — provides a starting point, not a comprehensive plan.
ROA Visualizer
Visualize RPKI ROA coverage across your routing footprint.
Global ASPA Coverage
Visualize the deployed RPKI-ASPA topology of the Internet, with optional cross-validation against CAIDA's inferred AS relationships.
Internet2 Customer Cone
The set of origin ASes Internet2 (AS11537) tags as participants, aggregated from R&E BGP data.
Anycast Explorer
Explore how anycast IPv4 prefixes are reached worldwide — RTT vs AS-hop count per vantage point, split by R&E vs commodity origin.
Understanding Reachability Gaps Due to Default Routes
Compare CAIDA Ark traceroutes from default-route vs full-localpref R&E vantage points to a more-specific commodity prefix — an overlaid AS-level Sankey shows where default-route paths fail to reach.
