Re: [tor-relays] New relay on dynamic IP address

[Mario Costa <mario.costa@xxxxxxxxxx>]

Just reporting back after some time. Today I noticed that my relay running at home with a dynamic IP got a guard flag again. So it’s totally possible for a relay to become a guard even after the authorities notice that it has a dynamic IP address.It must be noted though that the IP address didn’t change since it lost the guard flag the first time.

It looks like I had it wrong when I concluded that after the first IP change the relay wouldn’t became a guard anymore.

For reference, the relay fingerprint is F942EE73F1B8E39125F617FA85E80E4C9E540A2E.

It started back up with about 6 connections, but was back at a full 3000 in a few hours.  I've never had a guard flag, even with my current 3+months tor uptime with the same ip address.  I only run a terabyte a month through it, so maybe that's too little, though it does have the fast flag.

Then it would start up again after midnight.  I asked if this was still worth it, and the gurus said yes.  So I'd say that a few ip changes are going to be small potatoes compared to turning the relay off for hours every night.
