Agree. The deploying cost of IPv6 is quite expensive. I started to work on
IPv6 and IPv6 transition since 2001. By that time, we optimistically think
IPv6 could replace IPv4 in 2 or 3 years giving its maturity of basic
protocols and massive advantages. Now, I have to say that we underestimated
the deploying cost, a lot. One more thing to be mentioned, IPv6 provides a
lot transition approaches to support IPv4/IPv6 coexist. So far, I have not
seen such efforts in HIP or Node ID. (I may volunteer to do so.) And in
order to obtain the biggest benefit of HIP or Node ID, globally deployment
is requested. Therefore, transition solutions may not solve the problems.
