Hi If you want to put up a national firewall then you shouldn't allow v6 until that v6 version firewall is ready. China on the other hand has it's v6 firewall ready and at this time difficult to overcome at massive size( for v4 vpn can solve the problem)

Developing countries with no IPv6 option have to use IPv4, the current policies forced them to become a buyer and that create a good IPv4 market.
Honestly? Most developing countries are skipping IPv4 completely or as much as possible. If Iran has really banned IPv6 they deserve to pay themselves sick for IPv4. Furthermore, RIPE NCC does not have enough IPv4 addresses to give Iranians, even if we as a community wished for a special Iranian policy.
