Hi, I would just point out that back in history Java used to want mapped IPv4 (net.inet6.ip6.v6only=0) if IPv6 was enabled; most people don’t want that which may be why IPv6 support hasn’t been enabled. I have no idea if this is still the case. > On 19 Feb 2025, at 10:40, Harald Eilertsen <haraldei@anduin.net> wrote: > > Hi, > > IPv6 support in Java on FreeBSD has been an issue for quite a while.
