Domain Name System (DNS)

The Domain Name Request System is the place to go to request new domains under CA.GOV.  It contains the definitive registry for existing third-level CA.GOV domains (xxxx.ca.gov) for state and local government entities (e.g., city, county, police or fire department, reclamation, water district, etc.).

Highlights

  • DNS registration for third-level domains under “CA.GOV” (i.e. DWR.ca.gov, CDT.ca.gov)
  • Built-in prompts to help guide users through required documentation for new requests
  • Built-in prompts to help guide users through proper nomenclature per policy (SAM 5195, SIMM 40A)
  • Access to your domains’ ownership information at any time
  • Annual reminders for domain owners to keep domains and contacts current

CDT coordinates registration renewals.

There are no charges for DNS administration.

Government entities can request new third-level domains (xxxx.ca.gov) via https://domainnamerequest.cdt.ca.gov/   Government entities with existing domains can submit technical / administration / maintenance requests to CDT via a Case/Request (or Service Desk if you do not have access to the CDT Request System)

  1. What is a Domain Name?
  • A domain name is used to locate an organization or other entity on the Internet. (e.g., cdt.ca.gov is the domain for the CDT web site)
  1. What is Domain Name System (DNS)?
  • DNS is an internet technology service that allows a domain name to be translated into an Internet Protocol (IP) address. A domain is a meaningful and easy way to remember a name that relates to an Internet address
  • DNS handles the mapping between host names, which we find convenient (cdt.ca.gov), and Internet addresses which computers understand (i.e.,10.1.1.1)

It contains a definitive registry for existing third-level CA.GOV domains (xxx.ca.gov) for state and local government entities (e.g., city, county, police or fire department, reclamation, water district, etc.)

  • CDT coordination of registration renewals
  1. What are the rates for DNS?
  • CDT coordinates registration renewals at no charge
  • DNS administration is provided at no charge
  1. How do I request changes to CA.GOV DNS services?
  1. How do I request a Secure Sockets Layer (SSL) certificate for my website from an outside vendor such as GoDaddy.com, GEO Trust, Digicert, etc.?
  • In order for CDT to approve a SSL certificate request the following information must be provided:
    • Which registrar/hosting provider was used (i.e. GoDaddy, Amazon, GeoTrust, DigiCert etc.)
    • The date of the request (CDT receives multiple validation emails from multiple providers in a few hours)
    • The fully qualified domain name (FQDN) requested (i.e. ‘www.CDT.ca.gov’ or ‘*.cdt.ca.gov’)
  1. What is a Fully Qualified Domain Name (FQDN)?
  • A FQDN is the complete name to specify a specific computer location in the hierarchy of a complete domain
    • For example, there may be two groups within the DNS Made Easy organization; sales and support. So we could use the sub-domains sales.dnsmadeeasy.ca.gov and support.dnsmadeeasy.ca.gov. If there was a specific system in the support sub-domain, the FQDN for this computer would be computer1.support.dnsmadeeasy.ca.gov
    • dnsmadeeasy.ca.gov is the FQDN for the web server for the entire DNS Made Easy organization. Whereas www.support.dnsmadeeasy.ca.gov could be the FQDN for the web server for only the support department inside of the DNS Made Easy organization
  1. What is Time To Live (TTL)?
  • TTL is the amount of time that your DNS record is cached in resolving name servers on the Internet, measured in seconds. If your IP is dynamic (changes often) or if you plan to move your computer to another IP, it is recommended to set your TTL to a lower value to minimize this cache time. Once your IP is on a static IP or after you have transferred your system to the new IP, it is recommended to switch your TTL to a higher value
  • The higher the TTL, the faster the performance of DNS since most machines will have the value cached for a longer period of time, reducing lookups. However, a TTL that is too high often causes lengthy periods of downtime if your system ever needs to switch IPs
  • If your computer’s IP is static, then a recommended TTL ranges from 12 hours (43200 seconds) to 24 hours (86400 seconds). If your computer uses a dynamic IP, then it is recommended that your TTL is between 5 and 120 seconds
