Comment (by sqrt2):

 Contrary to what I wrote initially when I said Tor should publish
 "descriptors for each address", I think that the OR should not be trusted
 with deciding how exactly its addresses are going to be published, as not
 to make it possible to corrupt BridgeDB in the sense that statistics would
 show many bridges, but many of them are easily blocked as a group due to
 "treacherous" descriptors. (An odd type of attack, admittedly.) I agree
 that it is probably best if BridgeDB then treats each IP address as a
 separate bridge when it comes to handing out bridge addresses.

 Therefore, staying within the scope of this ticket, I think that Tor
 should publish just one descriptor with additional "a" lines containing
 both alternative IPv4 and IPv6 addresses. (I suppose for the BridgeDB side
 it would then make sense to open a separate ticket against the BridgeDB
 component?)
