Actually this is wrong.
I worked in telco, and dynamic is not the standard.
Dynamic is seen more in the cable modems then anywhere. Partially because they are on a loop, or ring in the neighborhoods.
Dial up are static. DSL can be static. Think of them more as a point to point on a copper pair. So start by looking at how many dial up users you have.
Next, DSL and cable CAN BE static, but, traditionally you have had to pay for them. Now I can't speak to ALL cable or telcoms. But I know here in the midwest, more times than not you have to pay for a static IP unless you are a business.
You can have an IP range, which some confuse with static. Where the last sequence changes.
There are a lot of factors that go into answering this. Some based on the technology you are using to connect, if you are residential or business, and what the provider offers.
Sorry there is no absolute.
