Connecting to the UCSD Network Via Ethernet With Mac OS X

Follow the steps below if you registered your machine to use a static IP to connect to the UCSD network via Ethernet with Mac OS X 10.3.x and above.

Images may vary slightly depending on the version you have. No configuration is needed if you're using DHCP.

Note: You need an active Ethernet connection registered with IT Services/ Hostmaster (faculty and staff) or ResNet (students), and your UCSD network username and password. If you've forgotten your username or password, see UC San Diego Accounts and Passwords.
