Dynamic Host Configruation Protocol vs Static Addressing

Static addresses are, as the name implies, hard-coded addresses that will only work on one specific network segment. Such addresses are intended for computers that are stationary and believed to be in continuous operation at one location, such as a desktop or workstation.

Reasons for wanting a static address:

  • Your computer does not support DHCP.
  • You want a fixed name and address because you run a web server.

Dynamic addresses, provided through a Dynamic Host Configuration Protocol (DHCP) service, work best with portable computers, such as laptops, that move between network segments all across campus.

Please note that the Dynamic Host Configuration Protocol (DHCP) will work just fine for assigning an address to a desktop machine, so if you're uncomfortable configuring the machine's default router, subnet mask, DNS servers and IP address yourself, DHCP will do all that for you.

Reasons for wanting a dynamic (DHCP) address:

  • You use a laptop.
  • Using DHCP makes it much easier to configure your machine.
  • DHCP can account for network addressing changes automatically.
