To reproduce:

Have a server that supports IPv6
Have an /etc/resolv.conf that has IPv4 and IPv6 address in it
run awl -4 or awl -6

Approximately half of the time something like dial udp4: address [IPv6]: no suitable address found will happen

What happens:

At 85a00bffbf/cli.go (L196), the program grabs a random IP address from /etc/resolv.conf

What should happen

85a00bffbf/cli.go (L196) should be refactored to only return IPv4 addresses if -4 is passed or IPv6 addresses if -6 is passed
