Hello,

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.

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

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

DHCP lease term

The Dynamic Host Configuration Protocol (DHCP) is an auto configuration protocol used on IP networks and an extension of the Bootstrap Protocol. DHCP allows for computers to be configured automatically to communicate with each other over an IP network without the need for manual setup by a network administrator. The implementation of DHCP relies on a DHCP server to hand out network configuration information to DHCP-capable clients that request an IP address (and other information required or useful in communicating with other devices on an IP network). In addition to an IP address, common configuration information served over DHCP includes a default gateway, subnet mask and DNS sever(s).

Transmission Control Protocol/Internet Protocol (TCP/IP) is the set of networking protocols that define end-to-end connectivity specifying how data should be packeted, addressed, transmitted, routed and received at the destination. This functionality is organized into four abstraction layers which are used to sort all related protocols according to the scope of networking involved.
