Todo o mundo Another aspect of DHCP that's important to understand is that the protocol utilizes broadcasts from client to the server in order to find the DHCP server and initiate the request. But on very large networks with hundreds or thousands of different IP subnets, it would be impossible to maintain a DHCP server per subnet. This is where the concept of a DHCP relay agent comes into play.
A DHCP relay agent is a way for the network to listen to DHCP server discovery broadcast messages from client devices, convert broadcast requests into a unicast packet, and forward requests onto the DHCP server that's in a different part of the network. This centralizes the management of IP addresses on your network.
There are plenty of other parts of DHCP that network engineers need to understand, which are beyond the scope of this primer. Understanding DHCP is a key part of a network engineer’s toolset that's likely to come in handy on a daily basis. |
