Which notation is used for IPv6 addresses?

Explanation:
IPv6 addresses are written in hexadecimal blocks separated by colons. Each address is 128 bits long and is shown as eight groups of four hex digits, with colons between the groups. This hexadecimal, colon-separated format fits the 128‑bit size neatly because each hex digit represents four bits, so eight groups of four hex digits exactly cover 128 bits. Dotted-decimal (used for IPv4), decimal dotted, and a binary-with-colons aren’t standard notations for IPv6. You may also see a compressed form using a double colon to skip sequences of zero blocks, but the core representation is hex digits with colons.
