One host (or server) running multiple Tor relays

Can a host (or server) have multiple IP addresses that are not in the same /16 network segment? Such a high-performance server can run multiple Tor and use different IP addresses.

Yup, most operating systems support configuring multiple IP addresses (in different subnets as well). It depends a bit on the specifics though. If it’s IP addresses that are routable within the VLAN, it can be as easy as making aliases on your network interface. Other scenarios might involve a bit more network configuration. You could check your operating system’s documentation for this or post more info here so people can help you :slight_smile: .

Limit is two Tor relays per IP address.
However, if you operate more than one relay, you should set MyFamily option correctly.

Yes, you can have 2, 10, 30 … IP addresses associated with the same server. There are quite a few operators running 30 or 40 Tor instances on the same server using something like ansible-relayor, etc…

You can also run multiple VMs on the same server, each having their own IP address and their own operating system.
