Re: V6 still not supported

Hello John

You’ve got something dead wrong about the history of IPR, there’s certainly no idea of monopoly. 

What we do when there’s market interest is write an RFC and RAND the rights. There is 25 years of IETF history to prove 
that. 

Another angle is that the change is in the host stack for the most part and we have no play in it. Without freedom for 
open source implementation the idea can not succeed.

You may wonder why we go through the hassle and cost?  The history of MPLS would certainly enlighten you on that. This 
is not a world where you can live without defensive weapons.

No one yet answered me on the technical aspects. That kind of baffles me.

Keep safe;

Pascal
