Manage resource records

If you use custom name servers, you must configure your resource records through your name server provider. Resource records are stored with name servers. Google Domains provides name servers at no additional cost and allows you to configure resource records directly. Learn how to manage name servers.

Learn about resource record fields

For examples of resource records, go to resource record types. When you add resource records in Google Domains, you must complete the following fields.

Host name

The Host name field indicates the object a resource record refers to. For example, a record might be relevant for your entire website, like example.com, or just a subdomain, like shop.example.com.

There are different ways to format the Host name field to specify what you want a resource record to apply to. If you’re not sure what to include in the Host name field, contact the service provider for your record type, such as your email service. Below are some common formats:

Apply a record to an entire domain

If you want a resource record to apply to your entire domain, like example.com, you can leave the Host name field blank, or add the “@” symbol. For example:

Host name

Type

TTL

Data

@

A

1H

123.123.123.123

Apply a record to a single subdomain

If you want a resource record to apply to a single subdomain, like shop.example.com, include the prefix in the Host name field. For example:

Host name

Type

TTL

Data

shop

A

1H

123.123.123.123

Apply a record to multiple subdomains

If you want a resource record to apply to multiple subdomains that don’t have any other resource records defined, you can use a wildcard record. For example, you could format the Host name field with an asterisk (*), followed by a dot (.), followed by your domain name. For example:

Host name

Type

TTL

Data

*.example.com

MX

1H

mailhost1.example.com.

Important: You can only use wildcard records for some record types. If not used properly, wildcard records may return unexpected results. For more detailed info, go to RFC 1034 (section 4.3.3) and RFC 4592. For more examples, go to RFC 4592 (section 2.2.1).

Type of resource record

The resource record types that you add. For example: A, CNAME, and MX.

Time-To-Live

To make internet resources more efficient, a device may store info about a website. To make sure resources are up-to-date, Time-To-Live (TTL) defines how frequently a resource record should be refreshed.

By default, Google Domains offers the most common refresh values:

  • 10 minutes
  • 1 hour
  • 6 hours

You may select Other and enter any value in seconds.

Record's data

The record's data depends on the resource record types. For example, an A record would include an IP address in the Data field. If you’re not sure what info to include, contact the service provider for your record type, like your email service for MX record types.

Create or modify a resource record

Important: Updates to resource records may take 24-48 hours to propagate across the entire internet. That means different internet users may get different results when they try to access or use your site during that time. This delay is due to the fact that for efficiency, most machines and browsers store or cache info about your website. That way, they don’t have to look up all of the details of the resource records every time the website is accessed.

Use the Time-To-Live (TTL) field to define how often machines and browsers should update your records.

Add a resource record
  1. Sign in to Google Domains.
  2. Select the name of your domain.
  3. In the top left, click Menu Menu and then DNS.
  4. Find "Google Domains (Active)." If you find "Custom (Active)," you use custom name servers and configure resource records with your name server provider.
  5. Under “Resource records,” click Custom records and then Manage custom records.
  6. Add field values in the grey boxed area.
    To include multiple records with the same Host name, Type, TTL, and Data values at the same time, you can use “Add more to this record.” This is known as a resource record set. For examples of how to format entries, check resource record types.
  7. To add another record, click Create new record > Save.
Modify or delete a resource record
  1. Sign in to Google Domains.
  2. Select the name of your domain.
  3. In the top left, click Menu Menu and then DNS.
  4. FInd "Google Domains (Active)." If you find "Custom (Active)," you use custom name servers and configure resource records with your name server provider.
  5. Under “Resource records,” click Custom records and then Manage custom records.
  6. Edit the Type, TTL, or Data fields directly, or to delete an entire record, click Delete Delete . If you want to remove one data field from a record set, click Remove cancel.

Important: if you click Delete Delete , it deletes an entire record set.

  1. Click Save.

Export resource records

To export the resource records you set up in Google Domains with a different DNS provider:

  1. Sign in to Google Domains.
  2. Select the name of your domain.
  3. In the top left, click Menu Menu and then DNS.
  4. Select Google Domains.

Tip: If you find "Google Domains (Active)" you currently use our default name servers. If you find "Google Domains" beside "Custom (Active)," you currently use custom name servers.

  1. Under “Resource records,” click Export DNS records.
  2. Choose the file type you want to export:
  • BIND: A BIND file is a .txt file many DNS providers commonly use to describe resource records.
  • YAML: A .yaml file is exclusive to Google Cloud DNS. This option only works if you export your DNS resource records in Google Cloud DNS.
