Manage DNS records (non-advanced interface mode)

This article describes operations in the non-advanced mode of the "DNS" product interface. Differences in interfaces modes are described in the article "About Gcore DNS".

Create a DNS record

1. Go to records settings

Open the “All zones” tab and select the domain zone you want to add records for. Click it or the Go to records button next to it.

Click Add record.

You will see the interface for adding new DNS record. Perform other steps in it.

2. Select record type

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.

3. Specify subdomain record belongs to

In the “Name” field, specify the subdomain the record belongs to. To add a record for:

• main domain (apex/naked domain; in the picture above it is examplesite.co) — leave the field blank;
• apecific subdomain — enter the name of this subdomain (for example, if you enter "one", the record will be created for one.example.com);
• all subdomains at once (wildcard record) — enter an asterisk (*).

4. Specify content of record

Fill in the "Content" 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"

5. Specify TTL

TTL (time to live) is the interval in seconds used by servers on the Internet to check if the DNS records for your domain have changed.

Example: A-record has a TTL of 300. You have changed the value of this record from “128.0.0.8” to “127.0.0.7”. Within 5 minutes, when requesting your domain, users will be sent to a server with IP 128.0.0.8 (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 127.0.0.7.

6. Complete configuration and create resource record

After completing the configuration, click the Add button. 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.
