Missing ip addresses in DHCP

Hello,

I am having a problem with a DHCP server. I am very low on available
addresses. When I look at the address leases I see alot of missing addresses
within the scope. I checked in DNS and do not see the "missing" ip addresses.
I cannot ping the addresses either so I don't believe they are statically
assigned.
Not sure how to resolve this.

Thanks,

Hello James,

If the addresses are not in the DHCP list they are free for lease, so what
is your problem? Addresse are not alwys leased in the correct order from
1,2,3,4,etc.

The problem is that I have run out of ip addresses a couple of times and have
had to delete some ip addresses from DHCP that are from people that are only
in the location temporarily. Otherwise users cannot logon to the network.
There are over 25 ip addresses that are not listed in DHCP and are not in
DNS. The company is not that big and the 25 or so ip addresses would be all i
need for quite a while.

Hello James,

How long is your lease time? Lower it down to maybe 12 hours. Then the leases
will be deleted if not longer used.

Best regards
