Whois® DNS lookup

The Whois® DNS lookup app is essentially a bookmarklet for your home/starting page that will take you on our DNS lookups page, where you can do a DNS lookup(dig). The DNS lookup tool is a hosted tool that will give you the results of a dig or DNS lookup on a given zone. Search for all records or search for a singular record. DNS record types include A, AAAA, MX, NS, TXT, SOA, and SPF. If you don't want a bookmarklet, and would prefer to do single click dns lookups from a page that you are visiting, take a look at our DNS lookup extension for Chrome.
