I only know that it was (and I believe it still is) common in the US to get a static, or even multiple static IPs when you buy a broadband connection. In Europe however dynamic IPs are a lot more common. The real problem came up with 4.X (ioUrT) because the key isn't required anymore.
Well, let's wait and hope for the passport system (although that will scare the majority of interested people away).

Lol for the America!

Here you have to pay extra money to get a static IP. It's illegal to have one IP for more than 2 days straight otherwise.
