Configuring a /31 netmask on Gaia OS Technical Level
  • Adding an IP address with /31 netmask is not possible on Gaia OS

This behavior is by design.

The netmask /31 contains only the network address and broadcast address, without any available host addresses.
Therefore, when configuring a network with netmask /31 (per RFC 3021), it does not pass the Gaia verification of available hosts.
