You just create either an ipv4 or ipv6 socket. And then you can
bind to an address of that type if you want. Either all
addresses or a specific one.
Depending on the OS, binding to all addresses on IPv6 will also
bind to all the ipv4 addresses, which can be both handy an
annoying. On others you need 2 sockets if you want to listen on
both ipv4 and ipv6, which makes more sense.
