This converter was implemented per Dave Russell’s suggestion as a follow up to the MAC address to IPv6 link-local address online converter. If you are interested in the steps behind this conversion, they are simply a reverse of the original Mac->IPv6 converter.
Please note that of the various IPv6 notations, the one this script will expect is fe80::xxxx:xxxx:xxxx:xxxx.

Seems your converter doesn’t handle a few things, but a different online one does: http://www.sput.nl/internet/ipv6/ll-mac.html
Try this (SMCI board) in each: fe80::ec4:7aff:fe58:4707
You’re right, I didn’t implement shorthand notation in IPv6. I’m not a fan of it and don’t wish to support its proliferation so I did explicit addresses only. That or I’m just lazy 🙂 Thanks for the link.
Hey man I really dig your site! This converter is pretty neat, but what’s the procedure for when your first octet is 3 characters instead of 4? E.g. ‘4a8:…” instead of “a8df:…”
This most likely simply means that you are using a notation with leading 0s omitted (https://en.wikipedia.org/wiki/IPv6_address#Representation)
Now this post only talks about link-local IPv6 addresses which all start with “fe80” no matter what. What’s in the middle may have omitted leading 0s but the first couple of octets should always be “fe80”.
I hope this helps.
