What is an IP address?

 

An Internet Protocol address or IP is the set of numbers that identify your computer to other computers, such as a network printer at your job, or any computer connected to the Internet. IP version 4 (IPv4) is represented by four groups of numbers separated by periods,  such as 123.53.789.10. Since IPv4 addresses are running out, IP version 6 (IPv6) was developed. IPv6 is represented by eight groups of four hexadecimal digits separated by colons.

How do I set up an Internet connection?

 

  1. From the Apple drop-down menu choose System Preferences, or click the System Preferences icon at the bottom of your screen. 
  2. Click Network. 
  3. Click Ethernet interface.

    Note: If you cannot click Ethernet, check the bottom of the window to see if the yellow lock is closed. If so, click the lock to unlock it with your admininstrator password.
  4. Ensure the Location drop-down says Automatic.
  5. Next to the Configure menu, ensure Using DHCP displays.

    Note: Cox provides the DHCP information automatically.
  6. Click Apply
  7. Open and browser and test your connection.

How do I release and renew my IP address?

 

  1. From the Apple drop-down menu choose System Preferences, or click the System Preferences icon at the bottom of your screen. 
  2. Click Network.
  3. Click Ethernet.
  4. Click the Advanced button.
  5. Click the Renew DHCP Lease button. This both releases the old address and renews it.
