Knowing the real web host of a particular website is useful in all sorts of situations. For example:
- Competitive intelligence: knowing who hosts your competitors’ sites may help you understand their web strategy.
- Research: if you’re considering a new host, it can be useful to find out the hosts behind similar sites to yours.
- Stopping content theft: knowing the host of a website that’s stolen your content is the first step in filing a DMCA complaint.
- Dealing with malicious behavior: most hosts take a dim view of comment spammers, DDoS attacks, malware, etc. So reporting the site will often get the badly behaved booted off their host.
