Sorry for the late reply. java's ipv6 has issues as it relies on ipv4 to ipv6 address mapping. There is a 'with_ipv6' flavor which is described in the package description as follows: with_ipv6 Build the jdk/jre with ipv6 support. When the jdk/jre is built with this flavor, java will create only ipv6 sockets by default. Since ipv4 to ipv6 address mapping is disabled on OpenBSD, using ipv4 addresses will fail. Consequently, you may only use ipv6 addresses or you can start java with -Djava.net.preferIPv4Stack=true and can only use ipv4 addresses. Regards, -Kurt
