java - How to convert an address from IPv4 to IPv6 - Stack
An IPv6 (Normal) address has the following format: y : y : y : y : y : y : y : y where y is called a segment and can be any hexadecimal value between 0 and FFFF. The segments are separated by colons - not periods. An IPv6 normal address must have eight segments, however a short form notation can be used in the Tape Library Specialist Web interface for segments that are zero, or those that have IPv4 has 4 octets. But what is it called in IPv6-land? : ipv6 An IPv4 address is composed of four octets. We call it an octet because each of the four numbers in an IPv4 address has a bit length of eight bits. Eight bits (0b11111111) is 255 in decimal. One octet. IPv6 has eight 16bit numbers. For as far as I know there is no word for each number, is there? What do YOU call the IPv6 address parts - Cisco Community There seems to be some confusion as to what exactly you call the different address sections of an IPv6 address. The parts between the ':' delimiter. Or, the equivalent of an 'octet' in an IPv4 address. I hadn't realized until I stumbled across this IPv6 Addressing | Microsoft Docs IPv6 defines the following address types: Unicast address. An identifier for a single interface. A packet sent to this address is delivered to the identified interface. The unicast addresses are distinguished from the multicast addresses by the value of the high-order octet. The multicast addresses' high-order octet has the hexadecimal value of FF.

IP Addressing Guide - Cisco IP version 6 (IPv6) is the next generation of IP addressing. IPv6 quadruples the number of network address bits from 32 bits (in IPv4) to 128 bits, which provides enough globally unique IP addresses for every networked device on the planet. IPv6 is an important protocol for the future of IP networking. More information can be found at IPv6 CIDR Calculator | UltraTools
IPv6 Address Types & Format Explained with Examples
Transition IPv6 addresses - To help with the transition from IPv4 to IPv6 the following addresses are defined: IPv4-mapped addresses are IPv4 addresses that have been mapped to an IPv6 addressable format. The address consists of zeros for the first 5 octets, followed by one octet of … MAC address to IPv6 link-local address online converter Sure, this isn’t actually a construct of the MAC to link-local IPv6 mechanism per se. Based on RFC 4291 section 2.5.6, a link-local IPv6 address is just “fe80” followed by 54 null bits followed by the Interface ID.The trick here is that the “Interface ID” is not the same thing as a mac address, I think it’s meant to be the new mac address but I have yet to see one in the wild.
