convert the first octet from hexadecimal to binary: 52 -> 0101001.

reformat to IPv6 notation 5274:f2ff:feb1:a87f. Other prefixes might require one to leave a single zero between two colons. Answer (1 of 6): Here is the MAC to IP address conversion process step by step: take the mac address: for example 52:74:f2:b1:a8:7f. The EUI-64 format only leaves one further chunk that could be all-zero - the last one - which the script above adds back in as a single zero. Thus even if the IID's first chunk is all-zeroes (that is, if the MAC started with 02:00), it would be elided too. That's because the fe80:: prefix already contains three zero-chunks (elided to the double-colon) adjacent to the start of the IID. Note that if you wished to repurpose this for other (arbitrary) prefixes, which you might since EUI-64 can be used in any scope (although it's advised not to use it for global addresses for privacy reasons), you'd need a slightly more convoluted sed script. as per common conventions for address brevity. Locate IPV4 Address or Link-local IPv6 Address for the IP address, or Physical Address to see the MAC address for that adapter.

Double-click the adapter for which you want to see the MAC address and local IP address. (b) elide any further all-zero chunks at the start of the IID In Windows Vista, click Manage network connections. (a) elide any leading zeroes in each 16-bit chunk and I must give kudos to above for a pure-shell (unless you count printf) answer above, which I was seeking.
