Since IPv6 is going to replace IPv4, should I develop my new application to support it?

Question

I develop applications using many languages and a few platforms. From what I am reading, IPv6 is going to be mainstream within then next 5–10 years, and that some ISPs even offe

Answer 1

The most up to date news that I have heard is that with NPA... IPv6 is really not going forward very fast, if ever. (Steve Gibson - GRC)

It might not be worth your time.

EDIT... obviously this was poor foresight that I should not have bought into. IPv6 is coming and will be needed. IPv4 will probably always exist, but applications should be able to handle both in the near future.
