Team Cymru Bogons
Team Cymru's Bogon list identifies IP addresses that should not appear on the public internet — unallocated address space, reserved ranges, and other 'bogon' IPs.

Impact
Low — This is not a traditional spam blacklist but rather identifies IPs from invalid address space.
Auto-expiry
Updates automatically as RIR allocations are processed.
What it lists
IP addresses from unallocated or reserved address space (bogon addresses).
How to get delisted
- 01If your IP is listed as a bogon, it means the address space was recently allocated
- 02Wait for Team Cymru to update their bogon lists (they update regularly)
- 03Contact your Regional Internet Registry (RIR) to confirm your allocation
- 04Contact Team Cymru if the listing persists after allocation is confirmed
- 05This is usually not something you caused — it resolves naturally
