This free tool will convert any domain name to an IP Address. Knowing an IP addresses is useful for many situations like locating the origin of unwanted emails or the source of virus and port attacks etc.
You can also use this IP addresses to perfom a reverse IP domain check to search for other sites known to be hosted on that same web server. Knowing the other web sites hosted on a web server is important from both an SEO and web filtering perspective, particularly for those on shared web hosting plans.
A domain name is a unique name that identifies a website. An IP address is a unique string of numbers separated by full stops that designed to allow one computer (or other digital device) to communicate with another via the Internet.
Domain names were created for humans and IP address for computer. A domain name is the human-friendly version of an IP address.
I'll explain domain name and IP address using a simple example.
In your mobile phone you store your friends contact number. When you touch the name of a friend, your mobile phone automatically dials the number you’ve saved for that contact. You don’t need to know where the person you’re calling is located, and you don’t need to even enter their specific phone number. Domain names and IP address related like this. When visitors enter your domain name into a Web browser, the browser uses your domain name to find the correct IP address and, in turn, passes back the website associated with that IP address.
