Now, IPv6 is the future, therefore CIDR notation has been introduced. It concatenates the IP with the network prefix mask in one bit - identifying a host on the subnet - using a backslash; and this is used today.
Instead of cockily dismissing, you should use the imagination of the inexperienced to progress, (sk)bitch.
But since it's possible to change the MAC address of many network cards or routers this wouldn't help, would it?
That is true, that's why I referred to it as a host identifier. But this is all talking about the future of IP.
CIDR notation would show the network prefix mask (derived from a net or subnet address) by counting the number of bits e.g. /26. I haven't seen these modified as they are set to correspond to the class of the network.
This would identify subnets, meaning that two hosts on the same network with internal ips handed out by DHCP would be recognized as one.
Nonetheless, I wanted to state that hosts can be identified on the Internet, however I don't advise this procedure.
