IPv6 address is 128-bit. IPv6 addresses are written in eight groups of four hexadecimal digits separated by colons, such as 2001:0db8:85a3:0000:0000:8a2e:0370:7334.
IPv6 uses 128-bit addresses, so the new address space supports 2128 addresses
8 octets comprised of 16 bits each for a total of 128 bits.

IPv4 addresses are 4 bytes. IPv6 IP addresses are 16 bytes.
IPv6 address has 2^128 address and IPv6 address is of 16 bytes and is represented in colon hex notation.
IPV6 is less vulnerable to DNS Spoofing IPv4 addresses use 32 bit or 4 bytes for addressing IPv6 addresses use eight bit segments.
Simplified header format. IPv6 has a fixed length header, which does not include most of the options an IPv4 header can include. Even though the IPv6 header contains two 128 bit addresses (source and destination IP address) the whole header has a fixed length of 40 bytes only. This allows for faster processing. Options are dealt with in extension headers, which are only inserted after the IPv6 header if needed. So for instance if a packet needs to be fragmented, the fragmentation header is inserted after the IPv6 header. The basic set of extension headers is defined in RFC 2460.

IPv4 addresses are 4 bytes. IPv6 IP addresses are 16 bytes.
In case of IPv4, the address has 4 bytes. In case of IPv6, the address has 16 bytes.
IPv6 address has 2^128 address and IPv6 address is of 16 bytes and is represented in colon hex notation.
A "hextet" in IPv6 consists of 2 bytes, or 4 hexadecimal digits (as in the example in the question), or 16 bits.
IPV6 is less vulnerable to DNS Spoofing IPv4 addresses use 32 bit or 4 bytes for addressing IPv6 addresses use eight bit segments.
I think you are mixing up two different protocols. IPv6 addresses are not hard coded into your adapter; MAC addresses are. It's totally different. IPv6 addresses are 16 bytes long and MAC addresses are 6 bytes long.
128 Bits. An IPv6 address is made up of 8 fields consisting of 16 bits per field. If you multiply 8 x 16 will get 128 bits. Each field is separated by colons unlike IPv4 which was separated by dotted decimal notation. A good link to go to to see the address and how sub-netting is done is on the related links below.
IN IPv6 we can find 128bits.

IP version 6, also known as IPv6, IP next generation, or IPng. It uses addresses of 16 bytes, instead of the 4 bytes used in IPv4.
