64:ff9b:1:: / 48 — A prefix for locally translated IPv4/IPv6 addresses. Addresses with this prefix can be used for multiple IPv4/IPv6 translation mechanisms like NAT64 and SIIT. [31] Compared to 64:ff9b:: / 96, these addresses contain their translated IPv4 address in positions 48-63 and 72-87. [30] This means that for every IPv4 address a ...
Unicast address assignments by a local Internet registry for IPv6 have at least a 64-bit routing prefix, yielding the smallest subnet size available in IPv6 (also 64 bits). With such an assignment it is possible to embed the unicast address prefix into the IPv6 multicast address format, while still providing a 32-bit block, the least ...
It is divided into / 48 prefixes, formed by setting the forty bits following the prefix fd00:: / 8 to a randomly generated bit string. This results in the format fdxx:xxxx:xxxx:: / 48 for a prefix in this range. RFC 4193 offers a suggestion for generating the random identifier to obtain a minimum-quality result if the user does not have access ...
English: A Table of CIDR prefixes for IPv6, it shows the number of corresponding equivalent subnets for each prefix, as well as the number of the interface identifier bits. Date 1 March 2020
The Dynamic Host Configuration Protocol version 6 (DHCPv6) is a network protocol for configuring Internet Protocol version 6 (IPv6) hosts with IP addresses, IP prefixes, default route, local segment MTU, and other configuration data required to operate in an IPv6 network.
The IPv6 address specification 2001:db8:: / 32 is a large address block with 2 96 addresses, having a 32-bit routing prefix. For IPv4, a network may also be characterized by its subnet mask or netmask , which is the bitmask that, when applied by a bitwise AND operation to any IP address in the network, yields the routing prefix.
This is a list of the IP protocol numbers found in the field Protocol of the IPv4 header and the Next Header field of the IPv6 header.It is an identifier for the encapsulated protocol and determines the layout of the data that immediately follows the header.
Since it would not be practical to manually provision networks at scale, in IPv6 networking, DHCPv6 prefix delegation (RFC 3633; RFC 8415 § 6.3) is used to assign a network address prefix and automate configuration and provisioning of the public routable addresses for the network. In the typical case of a home network, for example, the home ...
