Refresh and Non Refresh Intervals for DNS Scavenging

We have a lot of old dns entries listed from years past.

We are now setting up scavenging.

The question is

Setting up for 7 days Refresh and 7 Non Refresh.
Does that mean the pcs have up to 7 days to re up its timestamp
and then 7 more days past that to regrav its IP?

I am not as clear on that as I would like to be before I go ahead and set it.

Thanks

The no-refresh interval is the period of time in which a record cannot be refreshed.  This is the first seven days after a timestamp. This reduces replication traffic.

The refresh interval is after the no-refresh and is the time when refreshes are allowed.

Once both intervals have passed, the record becomes eligible for scavenging.

So if you keep all the defaults of 7 days, a record will not be removed for a minimum of 14 days and a maximum of 21 days from the last time stamp if you kept the scavenge interval at 7 as well.

Is it ok to manually delete old records?

And what happens after a record is scavenged?

Thanks

Once a record is scavenged it is deleted.

And Yes, it is OK to delete them manually but the purpose of scavenging is to reduce the overhead so you don't have to do all of the work.

Scavenging does not affect static DNS records by default, so if there are static, you will need to delete them manually as well.
