RDNS can also be very useful when tracking down network issues and was the original driving force of RDNS.
When pinging a website or IP address, one part of the output is the server’s RDNS record.
The absence of an automated process for changing NS records not only makes our signup process one step longer than we’d like, it also prevents Cloud Flare, and other 3rd party DNS operators, from doing a slew of other things that would benefit customers and the Internet as a whole.
For those who are not yet Cloud Flare customers, let’s run through the sign up process: When Cloud Flare customers enable our DNS services for their domain, we allocate and provide them with nameservers.
When you enter a domain name into your browser, the DNS system will find the IP address of the server the domain is associated with. It establishes what domain is associated with the IP address.
This is a useful setting to configure for anyone, but it is essential for customers running an outgoing mail server on their Cloud Server.
In this blog, we’ll introduce a significant problem that DNS operators like Cloud Flare face when trying to provide the best possible experience to our customers.
If you are a Cloud Flare customer, you’ll remember during the sign up process you were asked to login to your registrar account in order to change your nameservers (NS).
When customers install Microsoft Active Directory Domain Services (AD DS) in Windows Server 2008 or Server 2008 R2, a couple of issues sometimes come up.
Type in the name of the domain you want to delegate, in this case Intranet.
Type in the fully qualified domain name of the first domain controller in the child domain (for example, Child Domain One.
The NS record would adopt the following format: 0/24 NS ns1.
Return to the forest root server and use the Computer Management console to create a DNS delegation. Right-click on the Tand Forward Lookup Zone to select New Delegation from the context menu.
This means that after the sending IP address is checked, if the reverse DNS does not match the sending domain, then it is classed as “unauthenticated”.
