I tried the test program published earlier on NetBSD, "::1" is resolved
to "localhost", "IPv6:::1" is not. I guess IPv6: shall be stripped.

I get it working with this:

        if (strncmp(addr, "[IPv6:", 6) == 0) {
                (void)strncpy(abuf, addr + 6, len - 7);
                abuf[len - 7] = '\0';
        } else {        /* Strip leading '[' and trailing ']' */
                (void)strncpy(abuf, addr + 1, len - 2);
                abuf[len - 2] = '\0';
        }

I wonder if this is a but in NetBSD getnameinfo(3)
