The smaller and mid-sized web service providers buy the class C IPs that they allocate the customers they serve. Internet service providers offer the ability to provide dynamic (shared) IP addresses for their clients. The reason is that because they are shared, they are less expensive and are more well-known.

It doesn't simply blacklist a website based on its domain name but rather by its IP address, too. The search engines that browse a site, are able to identify it by its IP address since an IP address serves as the primary identification number for the domain. Internet service providers anticipate this possibility and, if websites are blacklisted they will assign new IPs to all other websites using the same dynamic IP address in the class C range.

Internet service providers set up firewalls and other hardware and software to ensure their hosting provider systems are 'clean' and free of malicious attacks. Since hackers and other malicious individuals are always trying to hack into websites and cause damage and their servers, internet service providers must implement measures to safeguard their servers and networks.
