Most of the subscribers will use dual stack connection and a small number of subscribers will use tunnel in case they dont have IPV6 ability.For small number of applications, pro

On the other hand, back-end management systems are not so urgent.CT should push the government to work out mandatory policies to give incentives to the CP/SP to introduce
