Comment (by karsten):

 Replying to [comment:2 teor]:
 > We should be careful that we are checking GeoIP for the remote address,
 rather than the address of any proxy. I think that 'address' is the remote
 address, and 'addr' is the proxy, at least in some places in the code.

 > If that's the case, let's check and then update the comments on the
 struct definition, because I can never remember which way round it works.

 Oh, okay.  Any hints on where to start to find out?

 Also, part of what makes me somewhat uncomfortable of using `address` is
 that it says "FQDN (or IP) of the other end" in the comment.  But we
 really want it to be an IP for `tor_inet_aton()`, or we're not counting it
 either.  When would `address` contain an FQDN instead of an IP?
