❓ FAQs
What is reverse DNS lookup?
+
Reverse DNS lookup is the process of finding the domain name associated with an IP address. It's the opposite of regular DNS lookup, which finds IP addresses for domain names.
Why would I need to perform reverse DNS lookup?
+
Reverse DNS is useful for email server verification, network troubleshooting, security analysis, and identifying the source of network traffic or potential threats.
Do all IP addresses have reverse DNS records?
+
No, not all IP addresses have reverse DNS records. It depends on whether the IP owner has configured PTR records for their IP ranges.
What's the difference between A and PTR records?
+
A records map domain names to IP addresses (forward lookup), while PTR records map IP addresses to domain names (reverse lookup).
Can I use this for IPv6 addresses?
+
This demo version only supports IPv4 addresses. IPv6 reverse lookups use AAAA records and have a different format, but the concept is the same.
