Multiple Choice

The maximum number of IPv6 addresses is:

IPv6 uses 128-bit addresses, so each address is a unique 128-bit value. With 128 bits, you can represent 2^128 different combinations, which is the total number of possible IPv6 addresses. This is vastly larger than IPv4’s 32-bit space (2^32) and would only be 2^64 or 2^256 if the address length were 64 or 256 bits, respectively. Since IPv6 is defined as 128 bits, the maximum number of IPv6 addresses is 2^128.
