Re: Scavenging or something else to cleanup duplicate DNS entries?

We are short of IP addresses. So, when a laptop if off the network
for more than a couple of days, there is a good chance the unused IP
will be automatically reassigned via DHCP to another machine. There
is quite a bit of IP address turnover in 7 days. Does this mean we
should set scavenging period to shorter than the default 7 days if we
were to enable scavenging?
There is a single DHCP server, but 2 DNS servers.
Would it be a good idea to turn off the option of DHCP clients
registering themselves into DNS and letting the DHCP server
exclusively handle the DNS registrations? Wouldn't that eliminate the
source of duplicate entries into DNS and thus eliminate the need of
scavenging after the fact?
I think duplicate entries are also occuring when laptops are carried
to different floors and meeting rooms where they may be assigned new
IP addresses in different subnets as it moves around the building even
within the same day. Will scavenging do anything about these
duplicate entries?
