 We implemented this for IPv4, but not IPv6.

 From https://github.com/torproject/sbws/issues/202:

 Split off #154.

 When IPv6 is more than a few percent of relay load, sbws should reset
 relay bandwidths on IPv6 address changes as well. (Tor doesn't measure
 IPv6 entry bandwidth separately, but we want to.)

 Here's what we'd need to do:

     Add a relay or_addresses attribute
     Add or_addresses to result
     Check any IPv6 addresses in or_addresses to see if they've changed

 }}}

 We should also store IPv6, since currently sbws is only storing IPv4
 addresses.
