Re: [tor-relays] why are some exit IPs missing from Exit IP DB?

Such "non declared" exit IP addresses (OR IP != exit IP) are found by exiting through every single exit relay to detect its exit IP.

Since exits can change their exit IP address at any time the exit list can never be 100% accurate by design.

Isn't this a bug in TorCheck? It assumes that every relay has its ORPort IP as its Exit IP (OutboundBindAddress), and most likely also assumes that each exit only has one IP.

I opened one a few days ago:
