[issue38907] Add IPv6 Dual-Stack control for http.server

[JIanqiu Tao]

JIanqiu Tao  added the comment:

"--no-dual-stack" seems to be a better argument name. "--ipv6-only" lead to 
ambiguity in a IPv4 only environment.

[issue38907] Add IPv6 Dual-Stack control for http.server

[JIanqiu Tao]

New submission from JIanqiu Tao :

In Python 3.8+, when we run the http.server in a PC that support IPv6, it will 
bind IPv6 socket normally. On Linux or some other platforms, it also bind IPv4, 
that's pretty good, but on Windows, it doesn't work and "--bind 0.0.0.0" have 
to be provided to make it works in IPv4 environment.
In another case, once someone only want the http.server provide service in IPv6 
environment, but linux will still bind IPv4 socket automatically.

Could we add a argument such as "--ipv6-only" for http.server and open the 
support of Dual-Stack socket by default?
