The same thing that stops people from getting access to your domain registration and changing the IP. You have a contract with your provider (ISP or DNS) which says that you own that IP/Hostname.
Your home IP address changes, but most business or commercial accounts are given a static IP address (or blocks of IP addresses) which never changes.
Aren’t IPs prone to change though?
If it does what’s stopping someone from somehow getting that IP and hosting a fraud site?
I think in this case it’d be the user not putting in any sensitive data or downloading executables to run from an internet radio.
