 Logs on ponticum fill up with warnings about badly formed
 X-Forwarded-For headers.  Most (all?) of them appear to be IPv6
 addresses.

 Bridges.is_valid_ip() recognizes IPv4 addresses only.

 I don't know if extending is_valid_ip() is the right thing to do but
 it might.  I haven't looked into other usage of it.
