Dig

dig (domain information groper) is a network administration command-line interface tool for querying Domain Name System (DNS) name servers.

dig is useful for network troubleshooting and for educational purposes. dig can operate in iterative command-line mode or in batch mode. If a specific name server is not specified in the command, it uses the operating system's default resolver configured in the resolv.conf file. If the query has no parameters, it queries the DNS root zone.

dig supports internationalized domain name (IDN) queries.

dig is a part of the BIND domain name server software. dig replaces older tools such as nslookup and host.

Usage

Appending ANY prints all records. 

dig yourdomain.com ANY

The output looks like this:
