This article is probably wrong. You can buy IP address blocks or parts of IP address ranges assigned to other people. There is a market in residential IP address blocks, particularly for VPNs, scraping services, DOS.

These will be servers running in a data centre that have been assigned an IP address that used to be owned by comcast and is still marked as residential. And the VPN provider will have paid a premium for it.

For disney, it'll be whack a mole with these ranges, and I'm sure the VPN are doing clever things to make the ranges look innocent.
