In addition to looking up a domain by IP, Whois lookup can also help you validate your website code with one of several Domain and SEO tools including CSE HTML validator, W3C HTML validator and the CSS Validator. Each WhoIs tool identifies errors in your source code so that you can fix things like missing closing tags, errors in character encoding and more. No matter what DNS information you are looking for, WhoIs can help you identify anything related to domain names quickly and easily.
