Static Connection
Static connection type is used whenever a known static IP address is assigned to the router. Additional
addressing information such as the subnet mask and the default gateway must also be specified. Up to three
Domain Name Server (DNS) addresses can be identified. These servers resolve the name of the computer
to the IP address mapped to it and thus enable you to access other web servers by typing the symbolic name
(host name).

DHCP Connection
Dynamic Host Configuration Protocol allows the router to automatically obtain a IP address from the server.
This option is commonly used when the IP is dynamically assigned and is not known prior to assignment.
