IPv6 Addressing

IP version 4 (IPv4)

A protocol that uses 32-bit addresses, limiting the number of unique addresses to approximately 4.29 billion.

Network Address Translation (NAT)

A method used to allow multiple devices on a local network to share a single public IP address by mapping their private IP addresses to it.

IP version 6 (IPv6)

A newer protocol with 128-bit addresses, allowing for a vastly larger number of unique IP addresses compared to IPv4.

Hexadecimal

A base-16 numeral system used in IPv6 addressing, employing digits 0-9 and letters A-F.

Abbreviation of Groups of Zeros

In IPv6, multiple consecutive groups of zeros can be abbreviated using a double colon (::) to simplify the address.

Dual Stack Configuration

A networking configuration that allows devices to use both IPv4 and IPv6 protocols simultaneously.

NAT 64

A translation method that allows communication between IPv4 and IPv6 devices.

DNS 64

A specialized DNS server that translates DNS requests from IPv4 to IPv6.

6 to 4 Addressing

A tunneling method allowing IPv6 traffic to be sent over an IPv4 network.

4 in 6 Tunneling

A method that allows IPv4 traffic to be sent over an existing IPv6 network.

Compressed IPv6 Address

An abbreviated form of an IPv6 address that removes leading zeros and uses double colons for groups of zeros.

16 Bits in IPv6

Each section of an IPv6 address is represented as 16 bits, totaling 128 bits for the entire address.

Transition from IPv4 to IPv6

The process of migrating from the older IPv4 protocol to the more advanced IPv6 protocol due to address limitations.

Relay Router

A specialized router required for 6 to 4 addressing to facilitate the transfer of IPv6 traffic over IPv4 networks.

Unique IP Address Space of IPv6

IPv6 provides an enormous number of IP addresses, allowing for 45 quintillion unique addresses per grain of sand on Earth.
