DHCP Static IP Assignment List
With DHCP, IP addresses are assigned dynamically; devices typically don’t have a permanent
IP address.
However, in some cases you might want to assign a static (permanent) IP address to a device, while
still using DHCP for the rest of the devices on your network. This is also known as “DHCP reservation.”
You might want to do this with, for example, a Web server, FTP server, media server.
