DHCP lists a false negative - I want to undertstand how to correct it
Hello:
We have a small company that has a DHCP server that hands out private IP Addresses. The scope is from .100 - .175 (76 total IP addresses).
I saw that we only had 5 available IP addresses to give out yesterday so I began re-configuring some client devices from using DHCP settings to use Static IP addresses that are outside the DHCP range. I was able to free up 18 IP addresses last night.
From yesterday (shown below),
After I made a few changes (shown below),
My question is, why is our DHCP server showing 33 used IP addresses (shown below)
but, the display statistics show 55 are in use. Why are the numbers not adding up?

John is right on the DHCP lease times. If you have alot of changing clients like smart phones, you should lower that setting.

it sounds as if shortening the lease time is the way to go. Currently, the lease time is set to 2 days.
If I change that to under 24 hours, will that negatively affect any users that are active on the system? I am just trying to think if there will be any side-affects?
Perhaps I should wait for the weekend to change the lease time, when no one is in the office, what do you think?
