DHCP lease term

We have a subnet that only has a few IP's. What are the negatives of providing lease terms for say 2-24 hrs instead of 5-7 days? Network traffic...what else could be a negative?Thanks

'only a few ip's'
I would expect you to put the lease time to indefinite instead of such a short period (?)
Any specific reason why you want to do this?

As you mentioned, network traffic is the major drawback. I am not sure what on what server your are running the DHCP but memory and CPU could be an issue (most likely not though).

Most likely disconnections will occur for the re-lease process to take place.

Hope this helps.

Well we get laptops in and sometimes we re-image machines so we have to have available IP's. So our network team for some reason put a vlan with 240 ports for 250 available addresses. Dont ask me why. So we run into problems when machines hold the IP's for say 5 days.

What you also could do is exclude a few (1, 2 or 3) from the scope so you always have some available.
There is no drawback for changing the lease time.

Usually, admins set the lease time for devices that connect wirelessly shorter. This is because you have different users coming and going. If you have a lease time of 7 days and you have more than 254 users connect wirelessly within the last 7 days, you would have DHCP exhaustion.

The only real issue that you may want to consider is the size of the log file that records the DHCP data.
