Reverse DNS Lookup
Reverse DNS Lookup is a free tool to find hostname associated with an IP address.
# You IP address is : 18.104.22.168
Reverse DNS lookup is the process of querying DNS to determine the domain name associated with a particular IP address. This can be useful for identifying the hostname associated with a particular server, or for verifying that a particular hostname is correctly associated with an IP address.
There are several purposes and benefits of reverse DNS lookup:
Verifying the identity of a host: Reverse DNS lookup can be used to verify the identity of a host by checking that the PTR record of the IP address matches the hostname. This can be useful for security purposes and for detecting fraudulent activity.
Improving email deliverability: Some email servers use reverse DNS lookup to verify the authenticity of incoming emails. If the reverse DNS lookup of the sender's IP address does not match the domain name in the "From" field of the email, the email may be flagged as spam or rejected altogether.
Facilitating troubleshooting: Reverse DNS lookup can help IT professionals troubleshoot network problems by providing additional information about the host associated with a specific IP address.
Enhancing user experience: Reverse DNS lookup can improve the user experience by allowing domain names to be associated with IP addresses. This makes it easier for users to remember and access websites, as they can simply type in the domain name rather than the IP address.
Reverse DNS Lookup on windows
On Windows, you can use the
nslookup command to perform a reverse DNS lookup. To do this, open a command prompt and type
nslookup, followed by the IP address you want to look up, preceded by the
For example, to look up the domain name associated with the IP address
22.214.171.124, you would run:
nslookup -type=ptr 126.96.36.199
This will return the PTR record for the IP address, which is the domain name associated with it.
Reverse DNS Lookup on Linux
To perform a reverse DNS lookup on Linux, you can use the
dig command-line tool and specify the IP address you want to look up, preceded by the
PTR record type. For example, to look up the domain name associated with the IP address
188.8.131.52, you would run:
dig -x 184.108.40.206
This will return the PTR record for the Google DNS IP address, which is the domain name associated with it.
