    portability fix for systems that configure an ipv6 address by default, but use the ipv4 address for actual traffic.
    
    tweak decision logic for deciding if we should use the ipv4 or ipv6 tools.
    it would default to ipv6 as most interfaces have an unused ipv6 address, while
    actually using the ipv4 address. this fixes ping/traceroute functionality when
    using hostnames instead of ip addresses.
