Dmytro,

We discussed in private about this, but I learned from your article that 
there are two methods to generate an Interface ID of an arbitrary 
length: the default random, and the RFC 7217 stable plus privacy extensions.

When you say 'stable' - in what is it stable?

For my part, I plan to use this implementation in my projects of 
vehicular networks connected to cellular links.

Alex
