 There is
 [https://gitweb.torproject.org/user/isis/bridgedb.git/commit/?h=fix/14065
 -vanilla-ipv6&id=c1a3d4692270b592a3a2efb7d5a14af357f6f91c a regression
 test] for this, as well as
 [https://gitweb.torproject.org/user/isis/bridgedb.git/commit/?h=fix/14065
 -vanilla-ipv6&id=8507fa30378e85e90b71b54de2bcb2f9537936f4 a fix] for the
 bug, in my `fix/14065-vanilla-ipv6`
 [https://gitweb.torproject.org/user/isis/bridgedb.git/log/?h=fix/14065
 -vanilla-ipv6 branch].

 The problem was that, when a client requests IPv6, they are assigned
 `addressClass = ipaddr.IPv6Address` (otherwise, `addressClass =
 ipaddr.IPv4Address`). Later, in
 `bridgedb.bridgerequest.BridgeAddressBase.__init__()`, that `addressClass`
 was checked to determine if it is an instance of either
 `ipaddr.IPv4Address` or `ipaddr.IPv6Address` â the problem here being that
 it isn't ever an instance, it ''is'' the class, so the check to see if it
 was an instance would fail, and it would get reassigned to the default
 `addressClass = ipaddr.IPv4Address`, causing IPv6 request to return IPv4
 addresses.
