The most impactful thing that could be done to improve privacy on the Internet would be for ISPs to rotate people's IP addresses daily.

Why don't they? 🤔

@ryanc some of they do, and it’s hell :/

@ryanc it would be horrible for anyone trying to self-host anything or maintain a TCP connection for more than a day, and for anyone trying to ban someone by IP. unfortunately, some ISPs do

@noisytoot @ryanc dynamic DNS providers exist to solve this problem

@noisytoot @ryanc well, the first of these two things.

Banning someone by IP has never been a good solution

@http_error_418 @ryanc they only solve it partially. not everything uses DNS or regularly re-resolves the domain after the initial connection (e.g. wireguard), and some things (e.g. IRC) rely on having a long-lived TCP connection that cannot migrate between IPs without disruption. also have fun sending mail from a dynamic IP address and having your IP reputation get influenced by whatever random person had it last

@http_error_418 @ryanc in many cases there isn't a better option

@http_error_418 @ryanc and dynamic DNS doesn't work so well when you're hosting your own DNS on the connection with a dynamic IP (you'd need to automatically update the glue records)

@ryanc it would mess up other kinds of tracking and only the ISPs would have the user/IP mapping, ISP data would fetch more money!
