[e2e] Discrete IP

[Pars Mutaf]

Hi Andrew,

China has IPv6 for example but I cannot talk to them.
I don't have to install IPv6 to talk to them. If one day someone uses IPv7
(it is their right), I don't have to install IPv7.
The fact that there is a version field doesn't mean that all versions are
supported.

Cheers,
