Google Domains supports DNS resource records and DNS wildcard records. All of these records have Name/Type/TTL/Data fields (see About resource records). A domain can have up to 100 resource records.
Resource records and nameservers
Please note that the records you configure in Google Domains only work when you're using the Google nameservers. If you are using custom nameservers, a message will appear at the top of the DNS tab and you should configure your resource records and wildcard records with your DNS provider.
More about resource recordsRecord sets
Google Domains groups records into sets for easier viewing and management. A record set consists of one or more records with the same name, type, TTL - and different data values.
When you create a record, if a set with the same name and type exists, the record is added to this matching set and the TTL is updated. If there's no matching set, a new set is created and appended to the list of record sets.
DNS resource records provide information about your domain and define the components that support your domain. Resource records are stored with nameservers and are accessed during DNS lookups. For more information and examples, see About resource records.
To add resource records, do the following:
- Click My domains and then click the domain name.
- Click the DNS tab .
- Scroll to the Custom resource records section.
- Add field values in the grey boxed area using the + icon and Add button.
To edit resource records, do the following:
- Click the Edit button next to a set. This will make all the records in the set editable.
- Click the + icon to add a record. Click the x icon to delete a single record.
- Click the Save button.
(As noted above, you can also add a record using the grey box. The record will be added to the matching set if one exists.)
Note: When you make changes to a resource record, it could take up to the length of the TTL time for the change to propagate. When you add a new resource record, it will be visible to Internet users in about 5 minutes.
To delete resource records, do the following:
- Click the Delete button to delete all records in the set
- On the pop-up, click Delete again to confirm.
(As noted above, to delete a single record, use the Edit button and the x icon.)
DNS wildcard records are used to match one or more subdomains – if these subdomains do not have any defined resource records. You can create wildcard records for DNS resource records and Google Domain synthetic records. For more information and examples, see About wildcard records.
Please note the following about NS resource records:
- NS resource records that identify your root domain (@ or example.com) – you don't create these records and these records are not displayed under the Custom resource records section on the DNS tab . Instead, these records are managed for you, either by Google Domains if you are using the Google nameservers or by your DNS provider if you are using custom nameservers. Only the nameserver identifier (ns-zdns-dev-1.prod.google.com) is displayed under the Nameservers section on the DNS tab . You can change the identifier (switch from Google nameservers to custom nameservers) but you cannot change the NS records themselves. For more information, see Nameservers.
- NS resource records that identify your subdomains (info.example.com, support.example.com) – you create these records by selecting the NS type under the Custom resource records section on the DNS tab . Once created, these records will be displayed under the Custom resource records section and you can edit or delete these records.
