Hi All,
Sorry in advance if this has been answered before but I can't seem to find
a clear answer.
I'm using

dhcpd 4.11 & bind9.8

I have forward and reverse zones being updated when a host takes a lease
without an issue.
and if a host takes a lease and the IP changes from the last time dns is
updated to reflect this.
But when a lease expires the DNS entries remain. I don't know is this by
design or an error in my config.
I'm wondering should DHCPD update DNS to remove an expired entry?
Thanks for any input and help on this
Kind Regards

Begin at the beginning,and go on till you come to the end: then stop.
