What is a PTR Record and Why It Matters?

A PTR record is a type of DNS record that maps an IP address to a domain name, performing the reverse function of an A record. Also known as Pointer records, they are essential for reverse DNS lookups, helping verify the legitimacy of an IP address and enhancing email deliverability. Email servers often check PTR records to ensure that the sending IP matches the domain, reducing spam and phishing risks. Accurate Pointer records also aid in network troubleshooting and can improve trust and credibility with ISPs and recipients, making them a vital component of network administration and security.
