Maybe you meant ILNP here? AFAIK, IPv4 and IPv6 are equal citizens for LISP.

Comparing GRE with LISP is like comparing /etc/hosts with the global DNS system. ;-)

I don't understand the comments about LISP and IPv4. IPv4 works just excellent with LISP. I have a IPv4 block at home 
which I multi-home over my IPv6-only DSL and IPv4-only FTTH line. 

LISP is pretty address family agnostic: IPv4 over IPv4, IPv4 over IPv6, IPv6 over IPv4, IPv6 over IPv6, all work 
without problems. 

Kind regards,

Job

Doing IPv4 LISP on any kind of scale requires significant additional prefixes which at this time doesn't seem so 
practical to me.
