UITS provides DHCP (Dynamic Host Configuration Protocol) service to the university’s wired and wireless networks. Every computer or device on a network needs an IP address to send or receive information on it. The DHCP service provides an IP address automatically to any computer that successfully authenticates on the campus networks.
DHCP allows you to move a computer, such as a laptop, to a different location without having to reconfigure the TCP/IP settings. For example, if a professor has a laptop which he wants to take from his office to a classroom, DHCP will allow the laptop to connect to the network in the new location without reconfiguring TCP/IP. Or, if a student has a laptop she wishes to use to access the network in various locations around campus, DHCP will automatically provide an IP address wherever she is.

The University of Arizona requires that computers connected to the UA wired network be registered before they can obtain configuration information automatically.
To register, you will need:
- Your NetID
- The hardware address (MAC address) of your network adapter (see documentation below)
Submit your MAC address at https://account.arizona.edu/dhcp/
- Only register MAC addresses for which you are responsible. If you register it, you assume responsibility for it.
- You may register multiple MAC addresses with one form submission by separating the addresses.
- New registrations are added to the running configuration every 30 minutes.
What is a MAC address?
A network adapter's hardware (MAC) address is a set of six pairs of hexadecimal numbers that uniquely identifies the adapter in your computer. An example MAC address is 12:34:56:78:90:AB (some programs will display the address as 12-34-56-78-90-AB).
The MAC address is not the same as the IP address. An IP address is a set of four numbers between 0-255 separated by periods. An example IP address is 126.96.36.199.
Your computer may have more than one network adapter (e.g., wired and wireless). Register them both if you will be using both on campus.
