Manage DNS records

In this article, you will learn how to create and manage DNS records in the Gcore interface.

Please note that the article is referring to a non-advanced interface. The toggle switch is displayed in the "off" position in the accompanying image:

If you want to configure balancing and dynamic response use a separate guide: Advance managing with balancing.

Create a DNS record

1. Navigate the All zones tab and select the domain zone you want to add records for. Or click three dots on the right and Go to records.

2. Click Add record.

You will see the interface for adding new DNS record. 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 about them in the article Supported DNS record types.

4. In the “Name” field, specify the subdomain the record belongs to. There are several 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 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. Now, when your domain is requested, 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.

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 HTTTS. 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 recording 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 in which you want to manage records (edit or delete). Or click three dots on the right and Go to records.

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

3. In the expandable block, make necessary changes in TTL or/and value.

4. To delete the record click the corresponding button.

5. Apply the new settings by clicking Save.
