How many bits are contained in each field of an IPv6 address?

The correct answer is none of the options provided.
An IPv6 address is a 128-bit address used to identify devices on a network. It is represented as eight groups of hexadecimal digits separated by colons, for example:
Each group represents 16 bits, and there are eight groups in total, making a total of 128 bits. Therefore, the correct answer is 128.
It's important to note that IPv6 was developed to address the limitations of IPv4, which uses 32-bit addresses, resulting in a maximum of 4.3 billion unique addresses. The larger size of IPv6 addresses (128 bits) allows for a virtually unlimited number of unique addresses, which is essential for the increasing number of devices connected to the internet.
