I also see that IPV6_V6ONLY = 1 . What does that one do?

From https://www.man7.org/linux/man-pages/man7/ipv6.7.html

If this flag is set to true (nonzero), then the socket is
restricted to sending and receiving IPv6 packets only. In
this case, an IPv4 and an IPv6 application can bind to a
single port at the same time.

If this flag is set to false (zero), then the socket can
be used to send and receive packets to and from an IPv6
address or an IPv4-mapped IPv6 address.

Since I don't use IPV6 here, would I want to set that to zero/false? It does not appear to be causing any issues (that I know of).

I'd just leave it set as it is then.
