IPv6 uses a 128-bit address space
IPv6 address has 2^128 address and IPv6 address is of 16 bytes and is represented in colon hex notation.
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.
Earlier version of IP address is IPV4 that version 4. Due to ever increasing demand of addresses we have to switch to new version that is IPV6. IPV6 has that much space that even if you assign IP address to every leave of tree on earth they will not be short for that.
IPv6 1) Header is fixed (20 bytes). 2) ICMP6, IP 3) Types of address: i) Unicast ii) Multicast iii) Anycast 4) 128-bit address. 5) Address space is 2^128. 6) Format of address : colon hex notation. 7) IPsecurity support is built in.
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 address
IPv6 will increase the address space to 128bits. This will allow for around 3.4x1038 unique addresses. That's a lot. More then we could likely use in the foreseeable future. Of course we said that about IPv4 as well.

Any host or user can get a public IPv6 network address because the number of available IPv6 addresses is extremely large.​ smb
