But shouldn't the rotation take place connection-wise instead of on a daily basis?
If a user browses with a given address and gets identified by one specific agent that shares that information with 3rd parties (e.g. a social network that collects and shares users' IP addresses), every time that happens the then generated new browsing data will have a solid past reference to which it will be added, thanks to that one correct identification.
Most ISPs have dynamic IPv4 addresses, but IPv6 removes that necessity. This WILL help tracking.
They might consider them dynamic but in 18 years the only time they ever changed was when I actually switched providers. They were essentially static IP addresses. With one ISP it was the same for 5-6 years.
Depends on your ISP, no? I've been in a few and for most of them I would have a different IP just by rebooting my router.
Im sure it will vary depending on the ISP, but I've just had a different experience. I put a dns record on a domain I had so I could ssh in because the IP never changed for years. But every ISP after dialup has never changed my address after installing. That includes att, charter, Comcast, Comcast again, att and att again, and some regional ISP I can't even remember the name of.
It was somewhat broken for a while on windows 10, but they fixed that in march.
