Add a resource record

Add a resource record

A resource record is a record of matching domain and domain information in the Domain Name System (DNS).

In DNS hosting, you cannot manage reverse resource records (PTR records), for If you want to  create or change a PTR record, create a ticket.

Add a resource record⁠

In DNS hosting, resource records are stored in groups — one group contains all the resource records of a domain with the same type. For example, a group of NS records contains four records pointing to Servercore NS servers.

If you do not already have a resource record group of the correct type for the domain, add a resource record group of that type. If you already have a resource record group of the correct type, add an additional value to it.

Add a group of resource records⁠

1. In the control panel, in the top menu, click Products and select DNS hosting.

2. In the Domain Zones section, open the zone page.

3. Click Add.

4. Select the type of resource records in the group — A, AAAA, TXT, CNAME, MX, NS, SRV, SSHFP, ALIAS, CAA, DNAME, HTTPS, SVCB.

5. Enter TTL or leave the default value. TTL is the time in seconds for which a resource entry in the NS server cache is considered up to date and does not need to be re-cached. The TTL of a group applies to all resource records in the group.

6. Enter the name of the resource record group — this is the domain for which the group will be created. You can create a resource record group:

   • for the main domain (zone name) — leave the field empty. For example, if you leave the field empty for the example``.com zone, a group will be created with the name example.com.
   • for a subdomain — enter the first part of its name. For example, if you enter first for the example.com zone, a group will be created with the name first.example.com.

7. Select the type of resource records in the group — A, AAAA, TXT, CNAME, MX, NS, SRV, SSHFP, ALIAS, CAA, DNAME, HTTPS, SVCB.

8. Enter TTL or leave the default value. TTL is the time in seconds that a resource entry in the NS server cache is considered up to date and does not need to be re-cached. The TTL of a group applies to all resource entries in the group.

9. Enter the value of the resource record, for example, for an A record, the IP address to be mapped to the domain name.

10. If you need to add another resource record to the group, click Add Value and enter the value of the record.

11. Optional: enter a comment — any additional information about the group, it will only appear in DNS hosting.

12. Click Add.

13. Wait for the added resource record group to propagate to the DNS servers. Propagation can take up to 72 hours.

14. Optional: check resource records. If resource records do not appear on DNS servers 72 hours after creation, create a ticket.

Add a resource record to a group⁠

If you add a resource record to an existing group, it will have the name and TTL that are specified for the group.

1. In the control panel, in the top menu, click Products and select DNS hosting.
2. In the Domain Zones section, open the zone page.
3. From the menu of the resource record group, select Edit.
4. Click Add Value
5. Enter a value.
6. Click Save.
7. Wait for the resource record to propagate to the DNS servers. Propagation can take up to 72 hours from the TTL of the group. TTL groups of resource records can be viewed in the control panel in the top menu, click Products → DNS hosting → Domain zones → Zone page.
8. Optional: Check the resource record. If the resource record does not appear on the DNS servers 72 hours after creation, create a ticket.

Available resource record types⁠

А	Associates a domain name with the IP address of a server on an IPv4 network. Unless an A-record is created for the domain, the site will not work
AAAA	Associates a domain name with the IP address of a server on an IPv6 network. Unless an AAAA record is created for the domain, the site will not work
ALIAS	Binds an alias domain to the main (canonical) domain so that the subdomain leads to the IP address of the canonical domain. Similar in logic to a CNAME record, but can be added for second-level domains and can exist with other resource records for the domain (except A and AAAA)
CAA	Indicates certificate authorities that are allowed to issue TLS(SSL) certificates for this domain name. If multiple CAs can issue certificates for the domain, a CAA record must be created for each CA
CNAME	Binds the additional domain to the primary (canonical) domain so that both lead to the IP address of the primary domain. A CNAME record cannot be added for a second-level domain. A domain with a CNAME record cannot have other resource records
DNAME	Binds all subdomains to the main (canonical) domain so that they lead to the IP address of the main domain.
MX	Indicates the server to receive incoming mail for the domain. If the domain has multiple mail servers, an MX record must be created for each server, indicating the priority for load balancing
NS	Indicates DNS servers where domain name resource records are stored. When you add a domain to DNS hosting, NS records for the domain are created automatically and cannot be edited or deleted. You can only create NS records for a subdomain
SOA	Contains information about the domain zone, created automatically when the zone is created in DNS hosting. SOA record cannot be edited or deleted
SRV	Specifies the location — hostname and port number of servers for specific services. For each SRV record, it also specifies the server priority and record weight for load balancing between servers
SSHFP	Contains the key fingerprint that is used by the server when connecting via SSH protocol
SVCB	Contains data for establishing a connection to the site: preferred protocol and its version, IP addresses and ports
HTTPS	Specialized analog of SVCB record for HTTPS connection establishment
TXT	Contains any textual information to be added to the domain settings. For example, it can store a unique token to validate domain rights or a DKIM key for outgoing mailings
