Shared hosting accounts on web servers all share a common IP address, the numerical Internet identifier that pinpoints all websites. The IP address is like a signature—and it's a signature that search engines can follow. Search engines are wise to monitor IP addresses because link farms and content farms often share the same IP address with each other.
