The campus Hostmaster handles the Domain Name System (DNS) for Berkeley.EDU and its subdomains. Hostmaster also assists in the assignment of Fixed DHCP addresses under certain circumstances. Hostmaster Services may also include these activities:
- Care and feeding of nameservers (both hardware and software),
- Registering IP addresses and hostnames for new network connections,
- Coordination of network connection moves,
- Changing assigned hostnames,
- Adding aliases and mail-forwarding records to existing hostnames,
- Creation of subdomains,
- Coordination with departmental hostmasters who have been delegated authority for their own (departmental) subdomains.
IP's and hostnames for new network connections
If you are requesting a new data network connection, you will be provided a dynamic IP address and hostname. Dynamic IP's are sufficient for most workstations and devices; a fixed DHCP address can be requested if you are planning to connect a host, such as a printer or server. Use the 'Connect to Data Network' form in the TelCat catalog to request new data network connections.
Moving or Disconnecting network connections
If you are planning to move or disconnect a data network connection, use the 'Move/Modify Existing Data Network Service' or 'Disconnect/Delete Existing Data Network Service' service request form. You can specify any IP/Hostname changes on the request form.

Other DNS requests
All questions about hostnames, IP addresses and the nameservers may be emailed to hostmaster@Berkeley.EDU or you may use the 'Hostmaster Services' form in the TelCat catalog to open a request. These may include requests to rename a host, add an alias to an existing hostname, add a mail forwarding record for a host, or requests for the hostname and IP address previously assigned to a existing network connection.
Timing of DNS changes
Requests for DNS changes may be processed at any time, though most are processed during standard business hours. The changes generally take effect shortly after 3am the next day, when the DNS servers are reloaded. Requests for specifically timed changes can sometimes be accommodated (please give Hostmaster 5 business days' notice).
