Ahhh. Light comes on :-)

This makes it a little awkward when we have resources that dhcpd does
not manage and we are having to insert manually.

Agreed. The issue being whether the name is being 'managed' by dhcpd as
opposed to whether there is an active IPv4 lease.

Any idea of when this might occur ?

Anybody got a utility for quickly generating and inserting DHCID records
in the meantime ?
