BGP routing view of the internet

bgp.netquirk.com is the read-only monitoring surface for the bgp-monitor service: server-rendered HTML pages and a small JSON API over the BGP updates streamed by the public routing collectors. No login is required to look up a prefix or an ASN; an account is only needed to set watchlists and alerts at my.netquirk.com.

Try it

/AS5466 — prefixes originated by AS5466 (live)
/prefix/8.8.8.0/24 — observers of 8.8.8.0/24 (live)
/prefix/1.1.1.0/24 — observers of 1.1.1.0/24 (live)

API

GET /api/v1/live/asn/:asn/peers — snapshot JSON
GET /api/v1/live/prefix/*prefix — snapshot JSON
GET /api/v1/live/ws — state-mutation websocket
