How Many Bits Are in an IPv6 Address?

Answer: The number of bits in an IPv6 address is 128 bits or 16 Bytes.

The IPv6 address is of 128 bits or 16 Bytes. It is represented using hexadecimal numbers. The 128 bits of IPv6 address are divided into 8 parts each part contains four hexadecimal numbers i.e., 16 bits. Each set of every four hexadecimal number is separated by colon. An example of IPv6 address is 0A12: 452D: 1234: AB45: 269D: 3782: 21C3: 4215. The IPv6 is the latest version of Internet Protocol i.e., IP.

Notation of IPv6 Address

The notation of IPv6 128-bit address is given below.

Conclusion

So, the IPv6 address is 128 bits or 16 bytes. The IPv6 is denoted in hexadecimal format which can further be converted into binary to obtain number of bits in IPv6 address. It contains eight quartets separated by colon. Each quartet contains four hexadecimal number and later these hexadecimals are converted to binary to get 16 bits in each quartet. Since, there are 8 quartet of 16-bits the total number of bits in an IPv6 address is 8 × 16 bits i.e., 128 bits.
