The other distinct difference is that IPv6 includes new address types such as link-local addresses. IPv6 addresses can be represented in many different ways. An IPv6 address consists of 128 bits (as opposed to the 32-bit size of IPv4 addresses) and is expressed in hexadecimal notation. You can see there are 128 binary values in an address, and we tend to show IPv6 addresses written as hexadecimal values. In some cases, it may be useful to convert an IP address to decimal format, which is a base-10 number.

The following chapter continues with additional features of IPv6. Better Header Format : IPv6 uses a new header format in which options are separated from the base header and inserted, when needed, between the base header and the upper layer data . Each "X" represents a group of hexadecimal digits. IPv6 addresses are formatted by 128 bits and organized into eight groups, each group containing 16 bits. Hexadecimal Format: IPv6 addresses are written in hexadecimal (0-9, a-f) rather than the decimal format used in IPv4. This document makes RFC 2374 and the TLA/NLA structure historic. Some special-purpose subtypes of global unicast addresses which contain embedded IPv4 addresses (for the purposes of IPv4-IPv6 interoperation) are described in section 2. Dec 28, 2024 · IPv6 is designed to replace IPv4, offering a much larger address space and improved features. Another difference is that the IPv4 address used in the IPv4-compatible IPv6 address must be a globally unique IPv4 unicast address.

By 1990 the IPv4 address-space issue was well understood, and the IETF was actively interested in proposals to replace IPv4. IPv6 header includes fields such as the source and destination addresses, traffic class, flow label, payload length, and next header. IPv6 (Internet Protocol version 6) is the most recent version of the Internet Protocol, designed to replace IPv4. It allows the native program to use the same address data structure and also the same socket when communicating with both IPv4 and IPv6 nodes. IPv6-Adressen bestehen aus insgesamt 128 Bit woraus sich eine Menge von 2 128 möglichen Adressen ergibt. (Note, there is no IPv5).
