asked on What is this greyed out local subfolder in dns? Can it be removed?
Just cleaning out my DNS and I see this greyed out local subfolder. It has a NS record that shows an old DC that has not been in use for awhile. Is it safe to delete?
Please see picture.
Thank you.

That is a delegation.
Someone created it in your zone as it isn't there by default.
As for if you can delete it that depends on if it is needed. If you didn't create it someone on your team may have and may know if it is needed for an actual delegation.

Delegation are created by system, Let say if you have Exchange server and You did configured autodiscover in your IIS and bind it to port 443 then you'll have autodiscover grayed out in your local DNS and you can;t remove it, because if you do, your DNS will not reply correctly to new Outlook version request and You'll not connect client to Exchange.

Thank you. This particular delegation has an old NS record (the dc was made and taken off many years ago). I also see the NS record in the same place as all the current NS records. Any harm in deleting this old NS record from dns?

No no harm in removing old NS records in fact if you run a dcdiag with dns flag it would probably indicate that the invalid NS a problem.
