How many combinations of IP there is?
4.3 billion possible
There are only about 4.3 billion possible IPv4 addresses, which engineers assumed would be more than enough in the 1990s. With IPv6, there are about 340 trillion trillion trillion combinations — specifically: 340,282,366,920,938,463,463,374,607,431,768,211,456. (Let’s just say 340 gajillion.)

How many IP addresses are in a 24?

What is IP address example?
An IP address has two parts: the network ID, comprising the first three numbers of the address, and a host ID, the fourth number in the address. So on your home network — 192.168. 1.1, for example – 192.168. 1 is the network ID, and the final number is the host ID.
