I *think* that getaddrinfo() provides this. You can try to build by adding USE_GETADDRINFO=1 to your makefile. It's not enabled by default because there are numerous bogus implementations on various systems. If it works for you it could be the best solution as other programs which work are likely using it. I don't know if it's safe to enable it by default on FreeBSD. Regards, Willy
