# InvalidIpAddress (/docs/errors/chain/InvalidIpAddress)

The `ip` argument to serve\_axon or serve\_prometheus is not a valid address for the declared `ip_type` (prometheus additionally rejects the zero address). Verify the IP encodes correctly as IPv4 or IPv6 and matches the `ip_type` passed.

Declared by the `SubtensorModule` pallet; it classifies to the semantic code [`invalid_argument`](/docs/errors/invalid-argument).
