Overview

Learn how to request and register a ucsd.edu or ucsandiego.edu host name for a UC San Diego computer.  Every machine (computer, server, printer, etc.) connected to UC San Diego's network must have an assigned IP address and host name also called a domain name. Use these steps to register your host name (machine) or to change existing names.

In the right place? If the host name does not end in .ucsd.edu or .ucsandiego.edu, see Register a Non-UC San Diego Host Name.

Critical Concepts

---

• Your system administrator usually is the approved representative to register names for all departmental machines.
• Names must not imply affiliation with other individuals, labs, or departments.
• Names cannot infringe on non-university trademarks.
  
  

Steps to Take

Review UCSD and department host name policy

1. Read Registration, Management, and Use of UC San Diego Domain Names: PPM 135-8 (PDF).
   • For a standard UC San Diego host name (ends in .ucsd.edu or .ucsandiego.edu), review sections III.B and III.C.
2. Ensure you comply with your department's regulations when choosing and registering host names by contacting your system administrator.

Choose your host name

Use these guidelines when choosing an appropriate host name:

• Servers and other machines offering services need names that make sense to the people using them. Names might include "www" plus:
  • Your own name
  • Project name
  • Department name (e.g., www.cse.ucsd.edu)
  • Lab name
• Names must not imply affiliation with other individuals, labs, or departments.
• Names cannot infringe on non-university trademarks.

Register your host name

If you meet the requirements above, you can either:

• Register a new machine (lacks an existing IP address and domain name):
  • Contact your department's system administrator. Many system administrators handle IP and host registration for their local areas.
  • If your department does not have a system administrator, fill out a registration form with ITS Service Desk for each computer you wish to register. ITS will e-mail your IP address(es) and name(s) to you.
  • If you're not sure who to contact or how to proceed, contact the ITS Service Desk, (858) 246-4357.
•  
• Make changes to a registered machine.
  Contact the hostmaster to:
  • Change a machine's existing name. (Include its IP address in your request.)
  • Request additional names (in DNS terms, "A records" or "CNAMEs").
