What is Reverse DNS?

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.

Why do you need external Reverse DNS service?

Being a network operator is a hard job. You have a lot of things to do. The Reverse DNS is something you can simply move to ClouDNS and free you from the tasks to support multiple DNS servers for authority DNS. With us, you are completely free to move away from your network the most DDoS Attacked UDP service - the DNS.

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. Scopri di più

The Reverse DNS hosting provided by ClouDNS is built on DNS Anycast Network which provides the maximum possible speed and security from any location in the world.

IPv4 Reverse DNS

ClouDNS provides both Primary and Secondary DNS for IPv4 Reverse DNS zones. Supported network ranges are:

/24 - 255 Indirizzi email.
/25 - 128 Indirizzi email.
/26 - 64 Indirizzi email.

/27 - 32 Indirizzi email.
/28 - 16 Indirizzi email.
/29 - 8 Indirizzi email.

/30 - 4 Indirizzi email.
/31 - 2 Indirizzi email.
/32 - 1 Indirizzo IP

IPv6 Reverse DNS

ClouDNS provides both Primary and Secondary DNS for IPv6 Reverse DNS zones. The supported network ranges are from /32 to /128

Zone DNS

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.

Instant DNS propagation

Our Managed DNS service operates under self-developed system with instant DNS propagation over all data centers included in our network. The web-based control panel allows our customers to monitor the propagation over all data centers in real-time. You can check anytime for any of your domain names what is the update status for each data center. In combination with low TTL values (as low as 1 minute) our customers can deploy any changes faster without any downtime.
