Running a high bandwidth Tor server requires a lot of IPv4 addresses, while IPv4 addresses are becoming quite scarce and very expensive. For this reason we started the process to get the current limit of two relays per IPv4 address increased to reduce the cost of running high bandwidth Tor servers. You can find our proposal on Tor’s Gitlab: https://gitlab.torproject.org/tpo/core/tor/-/issues/40744.
If you would like to support this proposal, let us know and we add your domain/nick to the issue :).
This topic will also be on the agenda of the Tor Relay Operator Meetup on 2023-01-28 19:00 UTC: https://lists.torproject.org/pipermail/tor-relays/2023-January/020973.html.
See you there!
