Having DHCP enabled in a corporate network setting is pretty much “de rigeur”. With the abundance of computers on these networks you pretty much have to. I say pretty much simply because you don’t “have” to. At the cost of some time at computer setup, and then not using DHCP you can take a large step towards securing your internal network. It is not foolproof of course and there are ways around it, but it is a good first step. Do any of you guys DHCP disabled on your corporate routers?
