IANA IPv6 Special-Purpose Address Registry Registration Procedure(s) IETF Review Reference Note Address prefixes listed in the Special-Purpose Address Registry are IANA IPv6 Special-Purpose Address Registry.These parts are Unicast Address and Subnet ID.IANA IPv6 Special-Purpose Address Registry Created Last Updated Available Formats Node part is used to identify the node itself.īeside this, we also divide network part into two. Network Part is used to identify the network and used for routing. IPv6 addresses are consist of two different parts. Here, instead of writing 0000:00000, we wrote :: In other words, if we have an entire field of zeros in ana address, we can use only one 0 for each colon. We can use double colon to shorten continuous zeros in an address. To overcome this, IPv6 has a “ double colon” shorten mechanims. To write all these zeros are very difficult for an IP address consist of 128 bits. There can be many zeros in many groups of an IPv6 address. we can not drop any zero at the middle or at the end of a group. Here,the importan point is this: Only the leading zeros an be droped. In the below examole, we drop the leading zeros. Leading zeros can be dropped to shorten the address. There is no need to write the leaing zeros in an address. These abbreviations are mentioned below with related IPv6 examplesĭuring IPv6 address creation, there can be leading zeros at each groups. In other words, there are some abbreviations that are used with IPv6 address. To do this we use specific abbreviatioins in IPv6 World. IPv6 addresses are very logn addresses, so sometimes we need to shorten these addresses. Each of these digits can be created with 4 bits. To understand the structure of an IPv6 address, let’s give an example:Īs you can see above, our IPv6 address has 8 groups and each group is seperated by colons. So, with these numbers, the address become 8 x 4 x 4 bit = 128 bits. IPv6 address consists of 8 groups (separated with colons) and in each colons, there are 4 digits. We can use both numbers and these letters (A, B, C, D, E, F) to create an IPv6 address. Beside, in Hexadecimal numbering system, there are 10 numbers and 6 letters (A, B, C, D, E, F). There are 10 numbers is the decimal numbering system. Different than IPv4, IPv6 addresses are written with hexadecimal digits. Simplified configuration (with auto configuration)Īs you remember, IPv4 addresses are written with Decimal numbers.These new benefits that comes with IPv6 are given below: These are the new features that IPv6 Brings. With the development of this new internet protocol, some new features has also created. This is almost 340 undecilion available addresses, nearly unlimited! So, almost 2 128 available addresses can be created with this new IP version. The new and the next generation version of IP, IPv6 has 128 bit address space. It was the foundation of Voice Over IP (VoIP). It was providing effective data transfer on specific frequencies. It is mainly developed for streaming video and voice as experimental protocol for research and development. So, what about IPv5 after IPv4? IPv5 has named as Internet Stream Protocol (ST) that has never become an official standard protocol. We can say that, IPv6 is the new Internet Protocol version that we will use alone or beside IPv4 on our network devices anymore. This new Internet Protocol version is IPv6 (Internet Protocol version 6). For the new technologies, more IP addresess needed and for this need a new IP version has developed. As you know, IPv4 Addresses were limited and exhaused shortly. IPv6 Address is the new generation IP address that is mainly developed to overcome IPv4 exhaust and its limitations.
