I am using http://www.kloth.net/services/nslookup.php to lookup dns records but they can only be looked up one at a time, eg MX OR CNAME etc. If I want to get a list of all them for a particular domain is that possible, using this?

You can select ANY from the drop down list on the tool you mentioned. This is an interface to Dig or some similar application. Dig is generally installed on Linux with a DNS server, but you may be able to install it separately.

Selecting ANY returns all entries for a particular domain. If forces the query to get an authoritative answer rather than an answer from your local DNS configured in your network settings.

If you want to use your own application, you still can only query one domain name at a time. That is because of how DNS queries work. There may be a tool that will let you provide a list, but it is still one query at a time on the back-end. You can use:

dig domain.tld ANY

where domain = domain name and tld = .com, .net, .org, and so on.

There are other tools, but dig is the best.

  • One thing worth noting regarding the ANY query type is that it does not necessarily do what one might expect if sent to a caching server. (It may just return what happens to already be cached for the specified name, not all records.) – Håkan Lindqvist Jul 13 '14 at 17:43
  • @Håkan Lindqvist You are right. Good point! That danger exists with any DNS that is not an authority really. It's like a box of chocolates, you never know what your gonna get. – closetnoc Jul 13 '14 at 22:56
