Jan-Piet Mens has created an excellent DNSSEC reference card that is freely available for download and/or printing:

The document currently contains:

• Information on signing and serving zones authoritatively
• DNSSEC configuration information for the BIND, NSD, Unbound, and PowerDNS name servers
• Tips for using DNSSEC with common tools such as “dig” and “drill”
• Information about configuring and using TSIG signatures
• Tables with values for algorithm numbers, digest types and more

It is a very useful quick reference document that Jan-Piet Mens has updated a couple of times since its initial publication and has stated that he is open to updating further based on feedback from others.
