# InvalidIpType (/docs/errors/chain/InvalidIpType)

The `ip_type` argument to serve\_axon or serve\_prometheus is not 4 or 6. Check the value being sent by the miner or client; only IPv4 (4) and IPv6 (6) are accepted.

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

## Remediation [#remediation]

Check the argument values against the operation schema

The same explanation is available in the terminal: `btcli explain InvalidIpType`.
