Do I need to enable DHCP for the community or village network? The following is a technical analysis on personal opinions.
My personal suggestion is to enable DHCP, but some people ask why China Telecom and China Unicom do not enable DHCP?
When DHCP is enabled, you can see that the boot speed is faster. I think there a
Normally if you have a cable modem or DSL, you get your home PC's IP address dynamically assigned from your service provider. if you install a home cable/DSL router between your modem and home network, your PC will most likely get its IP address at boot time from the Home Router instead. you can choose to disable the DHCP server feature on your home router and set up a Linux box as the DHCP server.

The predecessor of DHCP is BOOTP. In the NIC configuration of Linux, BOOTP is displayed. DHCP introduces a concept not available in bootp: lease. The IP address allocated by bootp is permanent, and the IP address allocated by dhcp
DHCP servers are usually used in network construction. In order to better understand this aspect, we will give a detailed introduction to the running principle and process of the DHCP address configurations implementation method.
