Reverse DNS is a service that associates IP addresses with domain names. While regular Forward DNS resolves domain names to IP addresses, Reverse DNS does the opposite. It allows you to look up the domain name associated with a given IP address, providing a way to identify the host or server corresponding with that IP address. It's commonly used for security and administrative purposes, such as verifying the authenticity of incoming email servers or identifying the origin of network traffic based on IP addresses.
Reverse DNS service provided by ClouDNS is a Premium DNS service for IP network owners and operators and it is not included in the Free plan. The Reverse DNS hosting is a business class service and supports both IPv4 and IPv6 Reverse DNS zones.

The service is very useful for those administrators who manage their own mail servers. Reverse DNS must exist for the IP address from which the outgoing e-mail is sent. The reason is that many mail servers on the Internet are configured to reject incoming mail from any IP address that does not have Reverse DNS (rDNS).
*Standards from the IETF (Internet Engineering Task Force) suggest that every domain should be capable of Reverse DNS lookup. Tìm hiểu thêm
The Reverse DNS hosting provided by ClouDNS is built on Anycast DNS Network which provides the maximum possible speed and security from any location in the world.
Reverse DNS provides valuable information about IP addresses, which can be extremely beneficial for a variety of reasons. Moreover, if Reverse DNS is configured properly, it can massively enhance the overall performance and security of a network.:
Improve your email deliverability rates by configuring Reverse DNS records correctly. By doing so, it proves the authenticity of your emails.
Quickly identify and resolve issues by tracing IP addresses back to their corresponding domain names.
Detect and prevent malicious activities, such as spam, phishing, and hacking attempts, by identifying the true source of IP addresses.
Establish a positive online reputation by ensuring that your IP addresses are associated with legitimate domain names.
ClouDNS provides both Primary and Secondary DNS for IPv4 Reverse DNS zones. Supported network ranges are:
/24 - 255 IP addresses
/25 - 128 IP addresses
/26 - 64 IP addresses
/27 - 32 IP addresses
/28 - 16 IP addresses
/29 - 8 IP addresses
/30 - 4 IP addresses
/31 - 2 IP addresses
/32 - 1 Địa chỉ IP
ClouDNS provides both Primary and Secondary DNS for IPv6 Reverse DNS zones. The supported network ranges are from /32 to /128
Each network range (IP block list) requires one DNS zone to be configured. For example, if you have /22 IPv4 network range, you need to separate it into 4 DNS zones for each /24 sub-network. There is no limit on the number of PTR records which can be configured into the DNS zone.
