[New-bugs-announce] [issue43079] wrong IP address range given for ipv4_mapped

[Al]

New submission from Al <awpythonbugs at sunnyside.com>:

https://docs.python.org/3.9/library/ipaddress.html

This documentation for the 'ipaddress' IPv4/IPv6 Manipulation Library incorrectly states the address range for 'ipv4_mapped' as ::FFFF/96 (which means 0:0:0:0:0:0:0:FFFF/96).  This is just flat out wrong.  There are some websites out there, e.g. APNIC, that also have this error.

The correct address range can be expressed by any of the following methods:
1) 0:0:0:0:0:FFFF:0:0/96
2) ::FFFF:0:0/96
3) 0:0:0:0:0:FFFF::/96
