If the IP address is the one that is issued by the provider, then if you change it you cannot access internet. Only computers that have automatic IP address assigning option can change the configuration. In many countries it is illegal to change the configuration.
DHCP stands for Dynamic host configuration protocol. DHCP is a piece of the TCP/IP protocol suite that handles the automatic assignment of IP addresses to clients.

"IP configuration" determines how your computers IP address is assigned. A "static address" is what would be set if you want to manually assign your computer an IP. A "dynamic IP address" would use DHCP or some other form of this to automatically assign your device an IP without an user intervention and usually should be set unless you need to make you IP set to something very specific.
By implementing DHCP, you would eliminate the need to set-up IP addresses manually. DHCP (Dynamic Host Configuration Protocol) simplifies the management of IP address configuration by automating address configuration for network clients.
