i have asked this question on a few related forums lately and have either been flamed out of it or given no response.<p>for me at least, there seems a fair bit to know to do it right. it might be that it's one of those topics that you learn organically and take for granted, but i registered a few domains recently and having worked in the design end of things i am in the process of getting the sites up. it has be stumped.<p>i would like to have an in depth knowledge of all the dns settings, how they function, security issues, how to apply sub-domains properly etc. maybe there is not much to know, but from the list of options at my registrar there seems to be enough to warrant a large drop-down menu (10 items). i don't know what i need to know.<p>anyone any pointers in exchange for muchas gracias?
Out of curiosity, who is your registrar?<p>I would recommend checking out Slicehost's articles and ebook on DNS topics:

From my experience, I would say the following are the most useful concepts to grasp:<p>* Knowing the difference between an A record and a CNAME record<p>* Understanding MX records (especially with the prevalence of Google Apps for email)<p>* Understanding SPF records (helps if you have a web app or form that sends mail)
