Hello,
To test or check Reverse DNS on a Linux/Unix system, you can follow these steps:
Open the terminal on your Linux/Unix system.
Type the command nslookup followed by the IP address you want to check. For example: nslookup 8.8.8.8
The command will return the name associated with that IP address, which is the Reverse DNS record. For example:
makefile
Copy code
Server: your-dns-server
Address: your-dns-server-ip
Name: dns.google
Address: 8.8.8.8
In this example, the Reverse DNS record for the IP address 8.8.8.8 is dns.google.
Alternatively, you can use the host command to check the Reverse DNS record. For example: host 8.8.8.8
scss
8.8.8.8.in-addr.arpa domain name pointer dns.google.
This command will return the same result as the nslookup command.
BenefitsCalIt's important to note that Reverse DNS records may not always be accurate or up-to-date, so you should verify the results with other sources if needed.
