DHCP weakness

Posted at — Feb 15, 2016

I like DHCP because static IP address can be tough to manage. A single lapse can cause holes in the IP pool not to mention as machines are decommissioned almost the same thing happens. There is also physical subnet vs logical submet. It can be a pain in the ass.On the other side of the coin DHCP makes some of those annoyances go away but creates a few of it’s own. DHCP can cause duplicate assignments if the DHCP server is restarted and the IPs not saved localy. DHCP also makes some network security harder. Of course MAC address to static assignments makes somethings easy…And then it’s all confused by containers.
