An IPv6 address contains how many hexadecimal quartets?

An IPv6 address is represented by eight hexadecimal quartets, which are separated by colons. Each quartet consists of four hexadecimal digits, meaning that an IPv6 address can contain a total of 128 bits (8 quartets x 16 bits per quartet = 128 bits). This structure allows for a vastly larger address space compared to IPv4, accommodating the growing number of devices connected to the internet.

The format of an IPv6 address is typically abbreviated for ease of use, sometimes omitting leading zeros and using double colons to replace contiguous segments of zero quartets, but the full representation still consists of eight quartets. Thus, understanding that there are eight quartets in a complete IPv6 address is crucial for grasping how IPv6 networking operates.
