Fighting spam and phishing emails is a never-ending battle, in which one of the key players is the DKIM record. It will guarantee the sender of a main, based on the link with the domain name, and will serve as proof that the email was not forged on the way.
What is the DKIM record?
The DKIM (Domain Keys Identified Mail) record is a DNS record (TXT DNS record) that a DNS administrator of a domain uses to set proof that the emails sent from the domain are legit through cryptographic authentication. On the other hand, the receiver will also use the DKIM record by performing a DNS query on the domain to verify the sender using the information in the header.
If you are researching what secondary DNS is, pretty sure you already know the relevance of DNS for the Internet, websites, sites’ owners, and users.
Knowing that proper performance and constant accessibility rely on DNS infrastructure, it is easier to understand the value of redundancy. No doubt, having DNS records saved in different servers offers attractive advantages for your business.
What is it?
Secondary DNS is a helpful mechanism to distribute DNS records (specific DNS zone) through different servers. Let’s put it this way. A primary DNS server, in the past also known as “master server”, informs a bunch of secondary DNS servers, also known as “slave servers”, about a change in the DNS zone. So the secondary servers have the instruction to request those changes to the primary DNS server to keep updated.
Making it simple, Secondary DNS is a solution for pulling DNS records from the main server to many others through the DNS queries and keep a copy of these DNS records.
