Description

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.

IT rant

I don’t know why it is that every time I want to download the simplest of modules I’m asked to download this great new package manager to end all package managers. Which results in this glorious 3 fold install sequence:Screen Shot 2016-01-07 at 1.40.19 PM“Installing is easy, Composer will take care of all dependencies! Ooops it doesn’t but PECL will! Oops just kidding I guess we’re back to apt.”

Not to mention all 3 package managers are independent from one another so changes in one don’t percolate to the others; thus throwing out the window their mission to resolve dependencies.

I’m flabbergasted by this trend and its unquestioned acceptance.
