DHCP is Dynamic Host Configuration Protocol, and it is a network protocol responsible for managing and automating the process of IP assignment so that devices can be easily accessible on a network. The idea of DHCP can be understood well on a router where you can say that the router acts as a DHCP device and when the computer boots up, it looks up for a DHCP server to connect. When there is no DHCP server or device in the range or if the DHCP protocol is misconfigured, then you will get the DHCP Lookup Failed error.

1. Too Many Devices might be connected to a DHCP Server
As we mentioned earlier, DHCP Lookup Failed error comes up when there is no DHCP device or server or if the DHCP protocol is misconfigured. However, the DHCP Lookup Failed error can also trigger when there are too many devices trying to connect to the same DHCP server. There is a SUBNET mask assigned to every device, which is also responsible for deciding how many devices can be managed by the DHCP server. Usually, the default SUBNET mask of 255.255.255.0 with an IP Address of 192.168.X.Y is used, and that is also the reason why if you have more than 200 devices connecting to a DHCP server then, it can cause issues. If you have more than 200 devices connecting to the same DHCP server, then you can switch to a Class A or Class B subnet.
Class A networks have the default subnet mask of 255.0.0.0Class B networks have the default subnet mask of 255.255.0.0
