It does not seem true. IP addresses are visible outside in: * DNS servers when you get a zone delegation (the most important reason why changing IP addresses is a pain), * some peer-to-peer networks like Freenet, which do not use the DNS. (There are also a lof of internal uses of IP addresses for instance in firewalls and SSH caches.) So, you actually have: 1) Phone numbers (very visible outside) 2) IP addresses (visible outside) 3) MAC addresses (completely invisible outside except for a few minutes in the ARP caches)
