Do most Communications ISP clients have unique static IPs?
Genuinely static, as opposed to just not changing very often? Depends on how much you pay. When I had cable internet it came with a static IP; with DSL I'd have to move to a higher (= more expensive) service level.
But in practice the IP only changes when I turn off the modem, which I normally don't do. Neither the computer nor the router factors in. In fact it's useful for when people think they've got you identified and then you duck behind the curtain and change IPs, mwa ha ;)
Then there are those remote satellite locations where each town has its own /30 block* so you may not be officially static, but in practice...
* Really. When a disproportionate amount of your traffic comes from Arctic Bay, you notice this stuff. /30 is extreme though; generally it's /27 or /28.
