Yes, you're seeing a lot of press about IPv4 and IPv6 today.
Yes, you should ask your ISP (gently) when they plan on offering IPV6.
The larger ISPs *are* working on it. Just most of them are not yet offering IPV6 to residential customers; they are still working out the final details of how to make that work. For most customers, this *probably* involves replacing one or both of the boxes in the home. Some small ISPs may not work on it terribly soon; it does involve major investment. Many small ISPs buy their "new" gear off ebay..
It is in their interest to support IPv6; trying to extend IPV4 with a large scale equivalent of your little blue router at home, and forcing several customers to share a single public IPv4 address, will break several things. Things like p2p - used by gaming, some chat and voice systems, and some file sharing systems. It will break the ability to run "servers" on your home service.
The ISPs will have their support costs go up answering questions about why specific things are broken, but web browsing works. The ISPs will also spend more and more money on the hardware that does this address sharing.
http://test-ipv6.com was mentioned here. I run that site. Do use it; and in particular, just make sure that for World IPv6 day, it says you should have no problems. This is true for 99.95% of you. You'll just keep connecting to those participating sites over your existing IPv4. If it *does* say you will have problems, take it seriously.
If it does say you have IPv6, and you don't *expect* it... see what the provider is. If it says "6to4" or "teredo", those are two methods to give you temporary addresses. Both protocols use hardware volunteered by various folks in the communities. They don't have any place to complain to if they fail. Teredo users - for most people - will find it only works for connecting to specific IP addresses, and not to web sites by name.
Hope this helps.
