How many IPS are there?

The number of IP addresses depends on the IP version considered (IPv4 or IPv6).

IPv4 Addresses

• IPv4 addresses are 32-bits long.
• This results in a total of 2³² addresses.
• Therefore, there are 4,294,967,296 IPv4 addresses.

IPv6 Addresses

• IPv6 addresses are 128-bits long.
• This creates a significantly larger address space: 2¹²⁸ addresses.
• Consequently, there are 340,282,366,920,938,463,463,374,607,431,768,211,456 IPv6 addresses.

In summary:

IP Version	Number of Addresses
IPv4	4,294,967,296
IPv6	340,282,366,920,938,463,463,374,607,431,768,211,456
