For example, the following DKIM key length is 411 characters: v=DKIM1; k=rsa; p=MIIBIjANBgkqhkiG9w0BAQEFAAOCAQ8AMIIBCgKCAQEAlDv2kr5/XYYmYzy1ynCe25/2AYsLaQtZMvKoXsa1W1qgFfKFKmMw6vhcuLkII8FA8gJG18p9wwoXoP5wNZZOC02u9rrgoZt8FsuQmO6b/QJKNSuHEECr6hVD+H9C9zS9ThuQk2qa3RtVO6apHCcw/DLpQ1DN14kNd7URNQlGZLKFgblGI1NwaCOLvUgqpFP/hOzk5veqG2qh50krPLrg6Lzjvd4pLx/5+n87yvLXian3ZAjcVZ1IqT9O7UQtPu1mwPbjBH+odpc6xF3ZUFUoHLDpgxYmwW3z7lD7vTLErgkhxpzEl1+xQwYKG8IM/ryO85cZ4ADRX7fqj/QUi1mzGwIDAQAB; In this case, the key must be divided into two sections where the first part will be 254 characters long while the second part will contain the remaining 156 characters: “v=DKIM1; k=rsa; p=MIIBIjANBgkqhkiG9w0BAQEFAAOCAQ8AMIIBCgKCAQEAlDv2kr5/XYYmYzy1ynCe25/2AYsLaQtZMvKoXsa1W1qgFfKFKmMw6vhcuLkII8FA8gJG18p9wwoXoP5wNZZOC02u9rrgoZt8FsuQmO6b/QJKNSuHEECr6hVD+H9C9zS9ThuQk2qa3RtVO6apHCcw/DLpQ1DN14kNd7URNQlGZLKFgblGI1NwaCOLvUgqpFP/” “hOzk5veqG2qh50krPLrg6Lzjvd4pLx/5+n87yvLXian3ZAjcVZ1IqT9O7UQtPu1mwPbjBH+odpc6xF3ZUFUoHLDpgxYmwW3z7lD7vTLErgkhxpzEl1+xQwYKG8IM/ryO85cZ4ADRX7fqj/QUi1mzGwIDAQAB” The DNS management interface can then be added, so that the subdomain name is given in the domain […]
Solution attempts have been created for this problem, but all of these can only work if all servers on the Internet implement them. Querying SPF record For example, you can use the nslookup command in Windows to access record TXT, while under Linux the host command. Example of a Windows-based nslookup query: nslookup -q=TXT dotroll.com Server: google-public-dns-a.google.com Address: 8.8.8.8 Non-authoritative answer: dotroll.com text = “v=spf1 […]
How to create a DMARC record? Once SFP and DKIM are in place, you configure DMARC by adding policies to your domain’s DNS records in the form of TXT records (just like with SPF or DKIM). The TXT record name should be “_dmarc.your-domain.com.” where “yourdomain.com” is replaced with your actual domain name (or subdomain). Here are common tags used in DMARC TXT records: Tag name Required Purpose Sample v […]

Glue record It is common that one of the name servers in the delegated zone is in the zone itself. The ns1.dotroll.com record is in the dotroll.com zone, but there is a need to go up one level in the .com zone, otherwise we will be trapped. That’s why we need to pick up a record-breaking record. Such a foreign A record is called a […]
A domain name may have more SRV records. Example of the SRV record Two typical SRV records can be seen below: _sip._tcp.example.com. 3600 IN SRV 10 60 5060 bigbox.example.com. _sip._udp.example.com. 3600 IN SRV 10 20 5060 smallbox1.example.com. SRV record format Prioritycontains the priority value Fields name Description Name In general, the symbolic name of the service (_sip) is provided, and the service is protocols (_tcp or _udp). […]
A domain name may have several TXT records. Querying TXT record For example, you can use the nslookup command in Windows to access record TXT, while under Linux the host command.

For a domain name, you can set multiple MX records to increase the probability that the mail will be delivered to ensure redundancy. Querying MX record For example, you can use the nslookup command in Windows to access record MX, while under Linux the host command. Example of a Windows-based nslookup query: nslookup -q=MX dotroll.com Server: google-public-dns-a.google.com Address: 8.8.8.8 Non-authoritative answer: dotroll.com MX preference = […]
