How to Convert IPv6 Address to IPv6 EUI-64 Format

In this video, the presenter explains how to convert an IPv6 address into EUI-64 format. They start by discussing the basics of IPv6, noting that it is a 128-bit address compared to IPv4's 32-bit. There are two types of IPv6 addresses: Global Unicast (similar to IPv4 Public Address) and Unique Local (like IPv4 Private Address). Using the example IPv6 address 2001:db8:1:1:0013:ABAB:1001, the presenter breaks it down into three parts: Prefix ID (first 48 bits), Subnet ID, and Interface ID (or MAC address). They explain that to convert to EUI-64 format, you need the Subnet ID and the MAC address (00:13:AB:AB:10:01). The conversion process involves adding the hexadecimal value FFFE to the MAC address, dividing it into six parts, and then converting the first hexadecimal digit to binary. The presenter details the important step of changing the 7th bit and ultimately arrives at the final EUI-64 formatted address: 2001:db8:1:1:0213:ABFF:FEAB:1001.
