The ease of management, in my opinion, isn't worth the risk. And, as other posters have said, some servers/services require static IP addresses (domain controllers are a prime example).

Everything is virtualized, and so it takes all of two extra seconds in the customization wizard when I'm deploying a VM to set a static for a server. You could script the reservations from a CSV. However the reason why static IPs were better is because people are idiots and left their own winproxy/whatever programs running and so there were multiple DHCP servers all over the place Advantages And Disadvantages Of Dhcp cf18 Ars Tribunus Militum Registered: Feb 23, 2001Posts: 1928 Posted: Mon Sep 10, 2001 5:55 pm Let me guess...

DHCPv6 uses link-local (fe80::/10) IPv6 addresses when communicating between client and relay/server. Moving a machine to a new subnet? These DHCP packets are handled in software (not hardware accelerated forwarding). It automatically assigns and keeps tabs of IP addresses and any "subnetworks" that require them.

Enterprise organizations will want to take advantage of the centralized dual-protocol DHCP server to provide IPv4 and IPv6 addresses to client devices.
