Networks use protocols and addresses to route data packets to the correct destination.
IPv4 uses 32-bit addresses, which are often grouped into four 8-bit octets (e.g. 192.168.1.50). The mathematical expression for the maximum number of unique IPv4 addresses is 2322^{32}232 (which can also be written as 28×28×28×282^8 \times 2^8 \times 2^8 \times 2^828×28×28×28).
IPv6 uses 128-bit addresses, which are grouped into eight 16-bit blocks (e.g. 2001:0db8:85a3:0000:0000:8a2e:0370:7334).
Construct an expression representing the maximum number of unique IPv6 addresses.
