upgrade - At what point should I support IPV6 in my php scripts? -

I've got quite a bit PHP code and I'm wondering where at which point I started upgrading the script Should IPV6

I know that IPv6 has been on the 'list of things to do' for long periods, but in reality I have never seen a clear transit path when I need to start supporting it is.

IPv6 is widely adopted in some countries (such as Japan, China, Korea) and some big organizations (I have done an IPv6 workshop 6.) [Div = 1] years ago suggested that Support for IPv6 was necessary for all networking gear sold to the US government).

I think the small answer to your question is ... "When an important part of your target audience is IPv6".

For a public Internet site, the answer could probably not be "never", IPv6 meant that "we are running away from the IPv4 address" to solve the problem. Rather than IPv6, most organizations have gone down the path, extend the life of the IPv4 address.
