How to make sure Network Utility uses IPv4 address and not IPv6?
I need to do some ping and trace routes but they need to be done using IPv4 only. How can I make sure that I am using IPv4 in 'Network Utility' or alternatively in terminal.
Network Utility has no options for controlling this, the best you can do is to lookup the IPv6 address and you should in Network Utility be able to specifically ping that IPv6 address and the same for the IPv4 address. This does not ensure however that your pinging from an IPv6 or IPv4 address and the traffic might go via a gateway that links the two.
The best way to ensure a completely IPv6 ping and IPv4 ping is to use Terminal.app and the appropriate commands
ping = IPv4
ping6 = IPv6
Do man ping6 and man ping for more details. Similarly there is traceroute and traceroute6.
