Tech Stuff - IPv. Version 6 of the IP Protocol. Defined in RFC 2. RFC5. 09. 5 and RFC5. Everything about IPv.

BIG. An IPv. 4 address is 3. IPv. 6 address is 1.

This is about the number where each blade of grass on the planet could have its own IPv. IPv. 6 has been around since at least 1. CIDR initiative of the mid- nineties pushed back any, then pressing, need for IPv. The can was effectively kicked down the road. In retrospect this was probably a Good Thing .

This fact alone will keep users from implementation if they have any choice in the matter. Nevertheless, the internet is rapidly approaching the time - primarily due to IPv.

IPv. 6. The transition will be accompanied by much yelling, screaming, gnashing of teeth and grim resignation. It is not helped by the constant roll- back and fiddling with the IPv. More Info. Here are some of the reasons we need to transition to IPv. The 3. GPP (3rd Generation Partnership Project) decision to use IPv. DNS root- servers are advertising both IPv.

NAT. Imagine asking your Father to read his IPv. Got the picture. DNS and DHCPv. IP address disappear at the user level and auto- configuration (stateless or SLAAC configuration) can simplify address allocation. For IPv. 6 to work we must treat any need for a visible IP address as a system failure. IPv. 6 may have been, to use an unattributed quote, .

Nevertheless, there are a significant number of implementations, proving IPv. Much of the new IPv.

RFCs is, apart from routine maintenance, concerned with the impact of IPv. It is noted that RFC 6. April 2. 01. 2) now formally suggests that best practice protocol stacks should now include both IPv. IPv. 4. While IPv. IPv. 4 have been available, for many years, with mainstream OSs (Linux, BSD, Windows and others) and, due to its application in the mobile world, Android and other mobile centric OSs, most network boxes (DSL/cable modems) are still IPv.

High quality Open Source IPv. IETF may change this. Then again, perhaps holding one's breath may not be a sensible strategy just yet since it will be many years before all that IPv. NAT investment used by most ISPs will obsolete IPv. You need to be fairly comfortable with Hex stuff to handle IPv. Hexadecimal, Binary and Decimal)Contents.

IPv. 6 is naturally multi- homed. Second, an IPv. 6 address has a scope, that is, it can be restricted to a single LAN or a private network or be globally unique. The following table defines the types of IPv. IPv. 4 functional equivalent.

IPv. 6 Name. Scope/Description. IPv. 4 Equivalent. Notes. Link- Local. Local LAN only. Automatically assigned based on MAC. Cannot be routed outside local LAN.

No real equivalent. Assigned IPv. 4 over ARP'd MAC. Scoped address concept new to IPv. Multicast may also be scoped to link- local (RFC 4. Format. Site- Local. Optional. Local Site only. Cannot be routed over Internet.

Address Notation. An IPv. 6 address consists of 1. IPv. 4 address consists of 3. The user can choose the most efficient place to omit multiple zero entries. Examples. # raw ipv.

C1. AB: 0. 00. 0: 0. A0: AABC: 0. 03. F.

C1ab: 0: A0: aabc: 0. F. # alternate version - address with single 0 dropped. C1ab: :A0: aabc: 0. F. # the following is INVALID. C1ab: :A0: aabc: 0. F. Multiple zeros can be omitted entirely but only once in an address.

Examples. # omitting multiple 0's in address. F. # can be written as. IP). 0: 0: 0: 0: 0: 0: 0: 0. F. # cannot be reduced to this. F # INVALID. # instead it can only be reduced to. F. Experiment using the IPv.

Address Calculator. A hybrid format may be used when dealing with IPv. IPv. 4 addresses called an IPv. Mapped IPv. 6 Address (RFC 4. RFC 5. 95. 2 and RFC 6. IPv. 4 dotted decimal notation may be used after the first 6, 1. IPv. 6- IPv. 4 format x.

IPv. 4- Mapped IPv. IPv. 6 Prefix or Slash Notation. IPv. 6 uses a similar / (forward slash) notation to IPv. CIDR (Classless Interdomain Routing) which describes the number of contiguous bits used in its netmask.

Formally this way of writing an address is called an IP prefix but more commonly called the slash format. Examples. # single user address. IPv. 6 address allocation.

Experiment using the IPv. Address Calculator. IPv. 6 Address Types. The type of IP address is defined by a variable number of the top bits known as the binary prefix (BP). Only as many bits as required are used to identify the address type as shown in the following table (defined in RFC 4. Use. Binary Prefix. Slash. Description/Notes.

Format. The revised definition is a conceptual change and is both more flexible than the previous (RFC 2. RFC 3. 51. 3) definition if a tad confusing. IPv. 4 and NSAP prefixes are still allowed for but are now simply unicast addresses. Subsequent changes (from RFC 3.
