    Just wondering if anyone's ever used a DNAME record as opposed to a CNAME? Any problems or pitfalls (I know they're not really recommended in the longer term)?

    Situation is that I'm looking at a couple of event management web apps to manage sign-ups, etc. without building custom forms for our site all the time. To tie the URLs in with our domain, I was thinking of setting up an events.example.com subdomain on our site and pointing it towards our webapp.com/events/OurName page on the external site.

    Looks to me like a DNAME would give more options and allow us to link to specific event pages each time but am I missing something?

    I had never heard of a DNAME record before. From what I've casually skimmed, it appears to be a relatively new record so the main question I would have is how widely spread is support for it by DNS servers currently in use. I don't know if the DNAME spec is backward compatible with CNAME records for DNS servers not yet supporting DNAME.

    As for your intended use, I don't think a DNAME would do what you want. I would suggest looking at these two pages which offer brief descriptions of DNAME with comparisons to CNAME:
