I'm in the US. Been using the Internet and aware of my IP address situation for about 20 years. Not sure I've ever seen new ips handed out that often. Static means you pay to guarantee an unchanged ip. The exact specifics vary a lot but generally my IP address goes unchanged for months regardless of router reboots. It can change any time but in practice doesn't change all that often.
I just searched it and, even in the US, power cycling your router is the most common way to get a new IP.

Ok, so now I know that howtogeek is unreliable. That article was written by a moron.
they did not even seem to know that there is a such thing as a local and global/WAN ip address, there is never any mention of that in the article.
they say this like it's consistently true, no qualifiers. they gloss over the topic like it's simple and consistently works. it doesn't even consistently work for your local ip, your local ip is unimportant to anyone who isn't already physically on or hacked into your home network... not relevant to the discussion.
I just tried this though, just as a sanity check. I checked my WAN ip, unplugged my router and plugged back in, got the same ip again, unplugged the router for 15 seconds, still got the same ip.
The truth is, isps probably like to keep ips around for a while because precisely of people needing to have a semi-consistent identity to servers. If you could just evade any ip ban by rebooting your router, I feel like the internet would be an even wilder place, in a lot of bad ways.
Old cable guy here. Back in the day people had their modems jacked directly into their PC, so directly on the internet.
LOL, anyone remember needing something like Zone Alarm as a firewall?

Maybe it made sense to swap their IPs on reboot for their own, dumb protection? Maybe more likely that now we all have 24/7 modem/router/firewalls it costs less overhead to leave the dynamic IP alone? Maybe they just want us to pay extra for a "static" IP, even though it's basically that way for many or most of us?
Your last point is probably more on the money. I WFH and have to have my IP in a couple of whitelists. Since it never changes, no hassle.
Y'all quit downvoting OP. He's right in some cases, not so much in others.
US here, old cable internet guy. Can't speak for all the ISP's, but the several I've worked leave your dynamic IP alone unless you swap routers or modems. Weird because they used to swap your IP on reboots, or seemingly randomly. 🤷🏻♂️
Can't think of an easy, reliable way to do it without new hardware.
I've been able to get new IPs by simply power cycling my IP - though my IP also used to change randomly on its own also (I always presumed there was some network outage in the night when this happened though), I've also had quite a few different ISPs and they all worked like this, maybe it's more common in the UK.
I only know this is the norm because I host a website and media server from my home and had to update my DNS records everytime my IP changed, so I started to request static IPs
