Setting up a computer to obtain an IP address automatically

Configuring your computer to obtain an IP address automatically allows your networking device to assign a dynamic IP address to it.  Instead of manually entering the IP settings, which is time consuming, performing this procedure will ensure that the computer will get the correct TCP/IP settings.  This process is useful when:

  • Connecting a computer to a network with a DHCP server
  • Ensuring that the computer is getting the correct TCP/IP settings

To configure a computer to automatically get an IP address, you have to check the TCP/IP properties of the Ethernet adapter installed on the computer.  You will not be able to check or configure the TCP/IP protocols on your computer if an Ethernet Network Interface Card (NIC) is not installed on your computer.  If you are using a wired connection, make sure that the computer is properly connected to a network with a DHCP server.
