Do I need DHCP for Active Directory?

What are the 4 steps of DHCP?
DHCP operations fall into four phases: server discovery, IP lease offer, IP lease request, and IP lease acknowledgement. These stages are often abbreviated as DORA for discovery, offer, request, and acknowledgement. The DHCP operation begins with clients broadcasting a request.
What is DHCP handshake?
DHCP Handshake Discover – The client prompts a DHCP to discover message to identify DHCP servers. … Request – The client requests the IP address from the server. Acknowledge – The server acknowledges the new IP address that has now been designated to the particular device and completes the handshake cycle.

What is the best DHCP range?
Since the default DHCP address range is between 100 and 149, you’ll want to avoid all of the addresses between 192.168. 1.100 and 192.168. 1.149 when you’re assigning static IP addresses. That leaves the ranges from 2-99 and from 150-254 wide open, which is usually plenty for most home networks.
