Reverse DNS (rDNS): What it is and manage it on your VPS
What is rDNS?
Reverse DNS (rDNS) is a feature of the Domain Name System (DNS) that allows you to associate a domain name with an IP address. This is done by creating a PTR record in the DNS. A PTR record is a special type of record that contains the IP address of a domain name.
What is rDNS used for?
rDNS is used for a variety of purposes, including:
- Spam filtering: Spammers often use fake IP addresses to send spam. By checking the rDNS record for an IP address, email servers can help to identify and block spam.
- Security: rDNS can be used to help identify and track malicious activity. For example, if a hacker uses your IP address to attack another website, the website owner can check the rDNS record for your IP address to see if it is associated with any known malicious activity.
- Compliance: Some organizations are required to have valid rDNS records in order to comply with industry regulations. For example, financial institutions are often required to have valid rDNS records in order to comply with anti-money laundering regulations.
