I got bored playing with html forms today and what I ended up with is this nifty form that turns a given MAC address into a /48 IPv6 ULA prefix. The form POSTs this string to a cgi script which is essentially a quick re-write of the first Perl script I ever wrote (just added some html cruft to the STDOUT). I got the idea for the first script since I couldn't find a simple way to generate an ULA from my terminal. I had to open up a browser and find other similar web-based tools with a web search but several of these didn't seem to really follow the RFC, i.e. printing out a /64 instead of a /48 or printing out the prefix with no MAC address or even a field to give it one. Maybe some wayward network nerd standing up an IPv6 lab will find this useful :)
Limit of 1,208,925,819,614,629,174,706,176 ULA addresses per customer.
We know all about the habits of the ant, we know all about the habits of the bee, but we know nothing at all about the habits of the oyster. It seems almost certain that we have been choosing the wrong time for studying the oyster. -- Mark Twain, "Pudd'nhead Wilson's Calendar"
