Detailed explanation-1: -An IPv6 address is 128 bits in length and consists of eight, 16-bit fields, with each field bounded by a colon.

Detailed explanation-2: -128 bit was chosen because it provides enough IPs that we can waste a lot of them on things like IPv4 compatibility mechanisms, convenience, etc; and ensure that we don’t need crap like NAT, restoring end-to-end routability to the Internet.

Detailed explanation-3: -IPv6 is the successor to the first addressing infrastructure of the Internet, Internet Protocol version 4 (IPv4). In contrast to IPv4, which defined an IP address as a 32-bit value, IPv6 addresses have a size of 128 bits.

Detailed explanation-4: -The correct answer is 128 bits. The length of IPv6 is 128 bits.
