Why there is no www record in my DNS records? what happened?

a couple of months ago, i found that i cannot visit my own web site hosted on DH, after trouble shooting, i found that my www record is absent from Non-editable DreamHost DNS records. What Happened?

so i should add www manually to my DNS records, right?

then, which ip i should assign to this www record? (which is the most important problem for me)

Thank you

If you still have the directory with the files from when it worked, you could likely just add hosting to the domain, again, in the controlpanel, and let the “web directory” point til that directory. That’s were non-editable dns-records come from.

But it shouldn’t just disappear.
