What is Bogon announcement?

A bogon announcement is a BGP route for address space that should never appear in the global table — RFC1918 private ranges, loopback, CGNAT, TEST-NET, multicast, or reserved/unallocated blocks. Bogons almost always mean a misconfiguration or a leak and should be filtered by upstream providers.

Frequently Asked Questions

What is a BGP Bogon announcement?

A bogon announcement is a BGP route for address space that should never appear in the global table — RFC1918 private ranges, loopback, CGNAT, TEST-NET, multicast, or reserved/unallocated blocks. Bogons almost always mean a misconfiguration or a leak and should be filtered by upstream providers.

Where does this data come from?

Every event is detected from live BGP updates collected across 23 RIPE RIS route collectors worldwide, ingested into a ClickHouse time-series store and re-evaluated every few minutes. No third-party feed is resold; the analysis is original to WorldIP.io.

How often is the Bogon announcement feed updated?

The feed recomputes roughly every 5 minutes; it was last refreshed at 2026-08-15 04:30 UTC.

How do I subscribe to Bogon announcement events?

Subscribe to the Atom feed at /pulse/bgp/bogon.atom or poll the JSON endpoint at /api/pulse/bgp/bogon.
