Question

How do I make DNS changes?

Answer

To make any DNS changes, such as creating a host record (A-Record), modifying an existing record, or adding an alias (CNAME) to a host record, you must be the network administrator on the subnet on which you want to make the change. To request a change, send an email to hostclerk@ucdavis.edu.

1. Hostclerk will reply when we receive the request, within 1 business day. 
2. Hostclerk will confirm when the hostname is registered. 
3. DNS changes may take up to four hours to propagate after they are recorded.  

It is recommended, but not required, that each active host on a subnet be registered within the campus domain name tables.

What information do I need to include in the email?

Include the following (if applicable):

• subnet
• host name
• IP address
• Your name
• Email address
• Phone number
• Department

An example for requesting a new host name:

"Dear Host Clerk:

I am the network administrator for {subnet}, and I would like to create an A-Record for the following host name, {hostname.ucdavis.edu} for IP address {#.#.#.#}.

Sincerely,

{Network Administrator name}
{email}
{phone}
{department}”
