Hi Arash,
As an example in Iran there is only one exit point (AS12880 and AS48159 belongs to one organization) from country to global carriers controlled by government and as they have no LI platform yet on IPv6 there is simply no IPv6 service availability or possibility for Iranian service providers.
If your government is making your work impossible there is little the rest of the world can do about it. The world is out of free IPv4 space. The space that is reserved is for new entrants that need a tiny bit to connect to the old IPv4-only world. The days of running networks on only IPv4 are over. Everybody needs more addresses, and IPv6 is the only protocol that can provide them, so everybody needs to move. Including your government. I am sorry. I understand that your personal/business situation sucks in regard to this, but your government is the only one who can fix this :( Cheers, Sander
