Looking glass
Ask the routers yourself. Pick a router, a query and a target; the answer is the router's own output, unedited.
Queries
- BGP route
- The route the router uses for it, with every attributeIP address or prefix, for example 2001:db8::/32
- BGP community
- Routes that carry the communityStandard or large community, for example 218369:1:3
- BGP AS path
- Routes whose AS path matchesAS path pattern with * and ?, for example * 13335 *
- Ping
- Round-trip times from the router, from my own addressIPv6 address or hostname
- Traceroute
- The path from the router, from my own addressIPv6 address or hostname
Limits
Six queries per minute and forty per hour per address (per /64 for IPv6). Ping and traceroute: two per minute, and at most six times per ten minutes to the same target. For long-term measurements your own probe (RIPE Atlas, for example) works better.
Works without JavaScript too: the form reloads the page with the answer.
