Can you afford to wait?
Many system administrators seem content that if their IPv4 is working then there is no reason to deploy IPv6. The thought is that "IPv4 is not going to die any time soon so why should I bother with IPv6?"
Some predictions for the African region suggest that AfriNIC will continue to have IPv4 addresses available until 2014. "We have plenty of IPv4 space. We won't run out soon. Whats the point of putting IPv6 on my network."
The point is that its not about Africa. IPv6 becomes a requirement as soon as the first service launches that is IPv6 only and your customer wants to access that service. It is somewhat pointless having large amounts of IPv4 address space when the content that people want is not on the IPv4 Internet.
While it is likely that there will be much bartering and redistribution of IPv4 address space when the exhaustion phase happens in the next 100 days. Despite that, we can expect to see some IPv6 only services within quite a short period after the start of the exhaustion.
