ipa host-del to remove stale host/dns entries only

What would a command to remove stale host/dns entries look like? I'd love to create a cron that removes them every 7 days.

What do you mean by "stale"?
Remove them from where?

Stale as in DNS records for a deleted VM or machine and removed from an IPA server.

First, you need a way to identify the stale entries. Do you have that?
Second, you need way to update the server. Do you know how to do that?
A cron job would do those things: Identify stale entries and update the server accordingly.

Generally speaking, we’re happy to help if you run into problems, but we don’t have enough information to do it for you...and that’s not how the forum works anyway.

I guess a better question would be how to identify stale entries. DNS scavenging and aging for Windows is a setting but is there something similar for linux?

Updating would be a cron job running a script that would just be like:

for server in servers:
ipa host-del

There appears to be, but it depends on exactly what you are doing. Something in this search may help...if not refine it to include specific information about your setup: bind9? AD? Whatever you're using. Note the "-windows" part to remove a gazillion not-Linux finds.
