Hmm. The inet = operator is marked hashable in 7.4 but not in 7.3 ...
I wonder if that is a mistake? I recall looking at the datatype and
deciding there were no insignificant bits in it, but that could be
wrong. Or it could be that the network() function is taking some
shortcut it shouldn't.
Is any of this data IPv6 addresses by any chance?

Could we see the specific values that join in 7.3 and fail to do so in
7.4?
