Make IPv{4,6}Address.version and max_prefixlen available on classes, not just instances #118710
Description
Feature or enhancement
Proposal:
Sometimes, when there is a function that can operate both on IPv4 and IPv6 addresses, it is convenient to pass it the corresponding type object (either IPv4Address or IPv6Address) as an argument. However, that function cannot access the properties version and max_prefixlen using those type objects, because they only work on instances. This can be worked around by constructing a dummy instance (e.g. t(0).max_prefixlen), but it would be more convenient if those properties could be used on the type object directly (i.e. t.max_prefixlen), because their value doesn't depend on the specific instance, only on the type.
The proposal is to make IPv4Address.version, IPv4Address.max_prefixlen, IPv6Address.version, and IPv6Address.max_prefixlen evaluate to 4, 32, 6, and 128, respectively. Currently, all those expressions evaluate to property descriptors.
