TCP_EnableIPv6=1 is it time to make this the default?

Currently, to use IPv6 in the environment, its necessary to add TCP_EnableIPv6=1 to notes.ini. Is there any danger in turning this on by default?

While it's certainly not ubiquitous, IPv6 is hardly an edge case any more in 2021 and I think the capability should be offered without having to add a new entry to notes.ini. Without IPv6 in the environment (I just tested by turning IPv6 off on my network adapter) the code falls back to IPv4, anyway.

How about adding IPv6 support in by default and allowing it to be disabled with TCP_EnableIPv6=0 should someone find a need to?

    I think if we also could set the order to "IPV4, IPV6" it can be a good idea. Otherwise port-binds could bind to IPV6 and not IPV4
