Of prefix choices is shown in the following table: and the number of resulting /48 prefixes per person. Is to compare it to a projected 2050 world population of 9.3 billion A reasonable way of evaluating a specific field length There is a direct tradeoffīetween having a Global ID field large enough to support foreseeableįuture growth and not using too much of the IPv6 address space There were a range of choices available when choosing the size of the RFC 4193 Unique Local IPv6 Unicast Addresses October 2005 3.1.1. Interface ID 64-bit Interface ID as defined in. Subnet ID 16-bit Subnet ID is an identifier of a subnet Global ID 40-bit global identifier used to create a L Set to 1 if the prefix is locally assigned. Prefix FC00::/7 prefix to identify Local IPv6 unicast | Prefix |L| Global ID | Subnet ID | Interface ID | The Local IPv6 addresses are created using a pseudo-randomlyĪllocated global ID.

#CLASHX IPV6 HOW TO#

This document defines the format of Local IPv6 addresses, how toĪllocate them, and usage considerations including routing, siteīorder routers, DNS, application support, VPN usage, and guidelinesįor how to use for local communication inside a site. In practice, applications may treat these addresses like global There is no conflict with any other addresses. If accidentally leaked outside of a site via routing or DNS, Internet Service Provider independent and can be used forĬommunications inside of a site without having any permanent or Allow sites to be combined or privately interconnected withoutĬreating any address conflicts or requiring renumbering of Well-known prefix to allow for easy filtering at site Globally unique prefix (with high probability of uniqueness). Local IPv6 unicast addresses have the following characteristics: Inside of a more limited area such as a site. They are notĮxpected to be routable on the global Internet. TheseĪddresses are called Unique Local IPv6 Unicast Addresses and areĪbbreviated in this document as Local IPv6 addresses. Unique and is intended for local communications.
