Tor relays autodetect changes in their IPv4 address, and publish a new
descriptor containing the new address.

When the client gets the new descriptor (1-4 hours after each change),
it will use the new IP address. Until then, the client would use its other

The directory authorities regularly check the reachability of each relay.
When your relay changes IPv4 address, some authorities might find it
unreachable before it finds out itself, and publishes a new descriptor.
This is probably why your relay does not have the stable and guard flags.
But your relay is still useful as a middle node. And it frees up guard
bandwidth to be used for direct client connections. This is particularly
useful right now, because guards are under extra load from some
clients that were added in December.
