I am using dhcp & dyn.dns(bind) in my network and
everything works fine, except the following issue.

some of my mobile systems roaming around the networks
and due to some reasons,those are not properly send
the release request when changing the network. Ex. a
notebook has ip address of and changed
to But my dns still shows only. my dhcp log shows as follows

Jan  7 09:52:21 dhcp dhcpd: if IN A note1.abc.com
domain doesn't exist add 302400 IN A note1.abc.com add 302400 IN TXT note1.abc.com
"31f0ea946091a19ad6167e1fb29ca6272d": domain already
Jan  7 09:52:21 dhcp dhcpd: if IN TXT note1.abc.com
"31f0ea946091a19ad6167e1fb29ca6272d" rrset exists
delete IN A note1.abc.com add 302400 IN A
note1.abc.com no such RRset.

I know that this is due to the existence of rr sets of
note1.abc.com as 

Is there any possibility to overwrite the existing
rrsets? or any other solution for this?
