[New-bugs-announce] [issue23103] ipaddress should be Flyweight

[Seth Bromberger]

New submission from Seth Bromberger:

ipaddress.ip_address instances should be flyweight. There's really no reason to make them mutable:

>>> a = ipaddress.ip_address("10.1.2.3")
>>> b = ipaddress.ip_address("10.1.2.3")
>>> id(a)
140066533772368
>>> id(b)
140066504622544

Especially with IPv6 and large numbers of addresses, it would be helpful not to have separate instances with the same underlying properties.
