What types of DNS records exist?

Main records: A, AAAA, MX, CNAME, TXT, NS, SRV, PTR, SPF, and SOA.
What is an A record?

What is an SPF record?
â–¼
An SPF record specifies which servers are allowed to send email on behalf of your domain, reducing the risk of spam.
What is TTL in DNS?

TTL (Time To Live) is the time a record is stored in the DNS cache. The lower the TTL, the faster record updates take effect.
