5 Best Free Online PTR Lookup Websites

Here is a list of best free online PTR lookup websites. PTR lookup is a DNS query used to obtain reverse DNS records using IP addresses. This lookup operation basically translates a valid IP address to its domain name. This operation is mainly performed to find the domain name associated with a specific IP address. If you also want to obtain PTR records using IP addresses, then check out these online PTR lookup websites.

Through these websites, users can quickly perform PTR lookup or Reverse IP lookup operations. To do that, users need to submit a valid IP address for a domain. On some websites, users can also choose a specific DNS server (Google DNS, OpenDNS, Yandex, etc.) for PTR lookup operation. In response to a PTR lookup query, servers provide a PTR Record, Domain Name, and TTL information. Users can copy and save the obtained PTR information. Some of these websites also explain PTR lookup and its significance. To help new users, I have included the necessary PTR lookup steps in the description of each website.

These websites also offer additional tools such as MX Lookup, TXT Lookup, CNAME Lookup, AAAA Record Lookup, DNS Search, and more. Go through the list to learn more about these websites.

Frequently Asked Questions

Where can I find PTR records?

To find PTR records, you would need access to the authoritative DNS server responsible for the IP address in question or have administrative access to the DNS settings for your own IP address range.

What is DNS PTR lookup?

A DNS PTR (Pointer) lookup is a type of Domain Name System (DNS) query that is used to find the domain name associated with a given IP address. In essence, it performs the reverse of a typical DNS lookup, which translates domain names into IP addresses (A or AAAA records)

How to do reverse IP lookup?

There are many online tools and websites that offer reverse IP lookup services. These tools are user-friendly and don't require any technical expertise. Simply enter the IP address you want to look up, and the tool will provide you with a list of domain names associated with that IP

Is a PTR record a reverse lookup?

Yes, a PTR (Pointer) record is used for reverse DNS lookup, and it is often referred to as a reverse lookup record. A PTR record in the Domain Name System (DNS) maps an IP address to a domain name, essentially providing the reverse mapping of the more common forward DNS lookup, which maps domain names to IP addresses (A or AAAA records).

Is PTR a DNS record?

Yes, a PTR (Pointer) record is a type of DNS (Domain Name System) record. It is used specifically for reverse DNS lookups, mapping IP addresses to domain names. In contrast to typical forward DNS records like A (IPv4 address) and AAAA (IPv6 address) records, which resolve domain names to IP addresses, PTR records resolve IP addresses to domain names. PTR records play a crucial role in reverse DNS, where the goal is to find the domain associated with a given IP address.
