A packet sent to a multicast address is delivered to all interfaces identified by that address.

A packet sent to an anycast address is delivered to one of the interfaces identified by that address.Īn anycast address identifies a set of interfaces (typically belonging to different nodes). One of the major shortcomings of IPv4 is that it uses a 32-bit address space. Global unicast addresses are globally routable and reachable on the IPv6 portion of the Internet.Ī prefix for link local addresses is always FE80::/64 with the interface ID be 64-bit length.Ī multicast address identifies multiple interfaces (typically belonging to different nodes). Nuggets IPv6 Compression & Addressing Primer IPv6 Addressing Primer IPv6 Compression and Concepts IPv6 addressing is a mechanism that was created to overcome the limitations of the current IPv4 standard. A packet sent to a unicast address is delivered to the interface identified by that address.įor the Unicast IPv6 Addresses, there are many types: Global unicast addresses, Link local addresses etc. The tool processes your request and gives you the following results.In general, there are three types of IPv6 address: Unicast IPv6 Addresses, Multicast IPv6 Addresses and Anycast IPv6 Addresses.Īn unicast address identifies a single interface within the scope of the type of unicast address.After providing, click on the 'Expand IPv6' button.

To expand the compressed IPv6 address, perform the following steps. However, expanding an IPv6 address helps to work with IP ranges more efficiently, and the several online tools make that expansion process relatively easy. Therefore, several rules are developed to compress the uncompressed IPv6 address. It must be challenging to memorize that IP address. Suppose you have to ping that IPv6 address. There are eight sub-blocks in IPv6 address, with each sub-block of 16 bits size.Īn example of IPv6 un-compressed form is 2001:4860:4860:0000:0000:0000:0000:8888 Using the two rules of IPv6 compression, edit each IPv6 address until it is in the shortest form possible, then click 'Check'. IPv6 is a 128-bit address, represented in hexadecimal notation. Use our exam questions to learn or revise today. The tool takes a compressed IPv6 address as input and returns the uncompressed IPv6 address by adding empty octets and full notations to the IP as contained in the original or full version of the IPv6 address. Our free A level Computer Science topics cover the AQA, CIE, OCR, Eduqas, and WJEC exam specifications. IPv6 Expand Tool converts the compressed/short form of IPv6 address into its original, uncompressed or full state.
