Hi Michiel!

It's not about hackers, it's about being tracked by advertising and marketing companies.

Not everyone got a static IP address inclusive. In Germany you would have to choose an expensive business tariff for that.

If you have to do that 3 times within a few weeks, you'd automate it.

Germany has a strong privacy law and ISPs are happy to charge you more for a business trariff with a static address/prefix.

I fully agree. The best approach would be to set dynamic prefixes as default and let the customer change that to static if he likes to.

 MvdV> prefixes.

Won't happen here :-(
