The control panel on the DNS zone page contains a list of zones that you can edit (the changes you make will be updated on our server within 30-40 minutes, but how quickly this will be visible to users directly depends on the Internet server settings provider through which the connection to the network is made). When you click on the zone name (let it be domain.tld in our example), the DNS editor page opens. Let's look at each of the fields presented on this page separately.

  • The “name” field has several options for filling:

    • @ - the “@” symbol means that the entry will apply to the zone on whose editing page you are located. In our case, this is domain.tld.
    • abc - a set of letters and numbers ("abc" was chosen as an example - you can enter your name) means that the entry will apply to a zone at a lower level than the one on whose editing page you are located. In our example, the entry will apply to the abc.domain.tld zone.
    • * - the “*” symbol means that the entry will apply to all zone options below the one on the editing page of which you are located. In our case, these are 123.domain.tld, abc.domain.tld, qwe.rty.domain.tld, etc.

  • In the “type” field you are offered several options. Let's look at each of them separately:

    • A - Used to indicate the mapping of a hostname to an IP address.
    • MX — used to specify the mail server for a domain.
    • CNAME — used to redirect a hostname to another name.
    • SRV — used to specify the server that provides the services of a particular service. Roughly speaking, this is analogous to an MX record, which specifies where email that is addressed to a specific domain should be delivered. Standardly supported by such protocols as XMPP (Jabber), SIP, LDAP. By using this type of record, you can host the Jabber server on a separate machine, and not on the same machine where the DNS A record points.
    • TXT — used to indicate additional textual information that the domain owner wants to communicate.
  • «MX preference» field available for filling only in the case of creating/editing MX type records. The numeric value specified in this field determines the priority of using the mail server. Since several mail servers can be specified for one domain, the sequence in which attempts to deliver a letter to these servers will be determined by the priority of the corresponding MX record. The lower the number in the “MX preference” field, the higher the priority of the server itself.

  • Field "value (IP/host.)" is filled in depending on the selected entry:

    • For the A record, the IP address is specified.
    • For the MX record, the name of the mail server is specified. If you write the name in full, you must put a period at the end!
    • For the CNAME record, the host name to which we set the redirection is specified. There must be a period at the end of the name!
    • For an SRV record, a string of the form “priority weight port value” is specified, where priority, weight and port must consist only of numbers, and the value is the full host name with a dot at the end.
    • For a TXT record, specify an arbitrary text string. Limitation - the entry can only consist of Latin letters, numbers, spaces and the following symbols:
    • . , ; : - = " / ~ ?
