This is a myth that persists, but as the above explanations make clear, that IPv4 traffic is only a fraction of the attack surface presented by networked hosts But sticking with IPv4 will get progressively harder to do so. An example of the advantage of IPv6 over IPv4 is not having to share an IP and getting a dedicated address for your devices. Using IPv4 means a group of computers that want to share a single public IP will need to use a NAT
