IPv4 v IPv6
The debate rumbles on sticking with IPv4 or switching to IPv6. Unfortunately that is not issue, the question should be "Should IPv6 supported by switching to dual stack?"
If you look at the stats compiled by google on the volume of traffic hitting their search engine https://www.google.com/intl/en/ipv6/statistics.html you can see that growth is 24.57%, however that shows volume of traffic at a weekend, if you look closer week day traffic is 20.79%. Everyone I work with uses Google which must mean a proportion of that traffic must comes from businesses.
If you look at the periods between December and January there is a spike in traffic which is becoming greater each year. Given this is the time for a seasonal holiday, when it the best time for businesses to test using IPv6 when most staff are way.
Enabling IPv6 requires planning and time, there are many organisations that have switched to IPv6 those that have Google, Facebook, Linkedln and others which have taken years. At what point do you start your IPv6 support when traffic gets to 30%, 40%, 50%, 60%, 70% or 99%?
If you assume that all current IPv6 traffic home use, then there an significant number of IT people honing or have honed their IPv6 skills already. Search ISP forums for customers asking for IPv6, these are technical people not a normal user.
Planning to enable IPv6 support is a sensible, prudent and shows forward thinking and the ability to accept change.
To answer the question "Should IPv6 supported by switching to dual stack?", clearly it is yes.
