DNSSEC

DNSSEC (Domain Name System Security Extensions):

• Sign your DNS zone to add an additional layer of security to your domain’s DNS records.
• DNSSEC can be complex to set up and maintain, so it’s best to work with a technical specialist to ensure that it is done correctly.

A valid DNSSEC record for example.com would look like this :

"example.com. 86400 IN DS 12345 7 2 (49AAC11D7B6F6446702E54A16073B1607A1A41855200FD2CE1CDDE32F24E8FB5)" 

DNSSEC is related to email deliverability in the sense that it provides an additional layer of security for your domain’s DNS records, which in turn can help protect against phishing and email spoofing. It
