DNS @ A-record

Can anyone tell me what the @ A-record is for?

I had assumed it was a catch-all, but I also have a * A-record in a domain's DNS records. What's the difference?

@ refers to the domain itself.

i.e. for domain.tld, having
@ IN A 1.2.3.4
would mean that you'd have an A record domain.tld -> 1.2.3.4

Ah thanks tolien, I see.

So it's okay to change the @ record - I was concerned changing it may make everything else confused, or something. I'm assuming changing it doesn't effect the MX records at all?

Not unless there's an MX record with @ on the right hand side.
