Create a DNS record

1. Navigate to All zones and select the domain zone for which you want to add records. Or, click the three-dot icon on the right and then click Go to records.

2. Click Add record.

A new window will appear. Perform the remaining steps there.

3. In the “Type” section, select the type of DNS record you want to create: A, AAAA, NS, CNAME, MX, SRV, HTTPS, TXT, or CAA. Learn more in our article on supported DNS record types.

4. In the “Name” field, specify the subdomain to which the record belongs. Choose from the following options:

• Leave the field blank to add a record for the main domain (apex/naked domain; in the picture above it is sample-test.com).
• Enter the name of this subdomain to add a record for a specific subdomain (for example, if you enter one, the record will be created for one.sample-test.com).
• Enter an asterisk (*) to add a record for all subdomains at once (wildcard record).

5. In the “TTL” field, specify the TTL (time to live) in seconds. For example, an A record has a TTL of 300. You have changed the value of this record from 1.2.3.4 to 5.6.7.8. Within 5 minutes, when requesting your domain, users will still be sent to a server with IP 1.2.3.4 (this value will be stored in the cache of recursive DNS servers). But after 5 minutes, the DNS server will check the settings and see the new value of the A record and the DNS server will send users to the server with IP 5.6.7.8.

6. In the field, enter a value appropriate for your record type.

Examples of values for different record types

Record type	Value
A	The IP address (IPv4) of the server of the web page that will open by your domain name. Example: 128.128.128.128
AAAA	The IP address (IPv6) of the server of the web page that will open by your domain name. Example: 7625:0d18:1fa3:07d7:1f44:8a2e:07a0:678h
NS	The name of the zone you want to delegate your domain to. Example: ns1.smth.com
CNAME	The domain or domain zone name that your domain should refer to. Example: uuuuu8.cdn.co
MX	The name of the mail server that receives mail for your domain. Example: ASPMX.L.GOOGLE.COM If you are using multiple mail servers, fill in the “Priority” field for each server. The lower the value in this field, the higher the priority.
SRV	The canonical name of the machine providing the service. Example: sip.example.com
HTTPS	HTTPS is a resource record that provides information and parameters for how to access a web service available via HTTPS. Example: example.com. 1800 IN HTTPS 1 . alpn=h3,h3-29,h2 ipv4hint=1.2.3.4,9.8.7.6 ipv6hint=2001:db8:3333:4444:5555:6666:7777:8888, 2001:db8:3333:4444:CCCC:DDDD:EEEE:FFFF
TXT	Text information the record should contain. Example: logmein-verification-code=976afe6f-8039-40e4-95a5-261b462
CAA	Defines the certificate authorities who are allowed to issue an SSL/TLS-certificate for the domain name. The record consists of three parts which are separated by a space: CAA [flags] [tag] “[value]”. The “value” must be enclosed in double quotes (”). Example: 0 issue “comodo.com”

7. Click the Add button.

That’s it. The DNS record with specified parameters will be created. You can check if the created record has been added correctly using the Gcore DNS Lookup tool.

Manage a DNS record

1. Navigate the All zones tab and select the domain zone for which you want to manage records (edit or delete). Or, click the three-dot icon on the right and Go to records.

2. To edit the record, click the pencil icon next to the desired record.

3. Make necessary changes in TTL or/and value in the expandable block.

4. To delete the record, click the corresponding button.

5. Apply the new settings by clicking Save.
