Overall experience improves efficiency and lowers operational challenges
* Add native management routing (geo‑routing, failover, weighted records) directly within Azure DNS zones to reduce dependency on extra services. * Cost Efficiency: Offer bundle pricing tiers or discounts for high‑volume enterprise customers, or an option for cost‑optimized internal DNS zones. * Improved Error Diagnostics: Provide more descriptive error codes and guided troubleshooting steps in the portal or CLI.

It's easy to use and set up, but I've faced performance problems
I have experience with Quad9 and most other filtering solutions. Quad9 was working well initially, but it started slowing, so I switched to OpenDNS. I recently checked Tom's Hardware, an IT review site, and read a review of seven DNS filters. Open DNS was ranked the fastest, and Quad9 was second. Google was on there too, but they said it didn't filter enough.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"It is a scalable solution."
"The most valuable feature of Azure DNS is it works automatically after configuration. Additionally, the solution is secure."
"The solution is easy to use and flexible."
"The initial setup is straightforward and not that complex."
"The speed of the queries is valuable."
"The most valuable feature of the solution is that it is a stable product."
"Integration with other Azure services is good."
"Azure DNS provides end-to-end P2P connectivity and enhances security, making it more secure and reliable."
"The most valuable feature of Quad9 is that it is a free solution."
"Setting up Quad9 is straightforward if you know what you're doing, and it's easy to use overall."
 

Cons

"Azure DNS sticks mostly with the Azure native solution and doesn't scale well in a multi-cloud or hybrid environment."
"The solution should provide better pricing."
"What needs improvement in Azure DNS is visibility in terms of troubleshooting. It's similar to the area for improvement in Azure Network Watcher, where I can see how the source is going out if I'm troubleshooting a source destination. I can also see the destination. As for seeing how the packet travels, that's what should be improved. It's still lacking in visibility. Suppose I'm looking into backend machines, and if I'm hitting another NPM machine or any machine on the other side, there should be visibility. The tool should tell you that a specific machine is passing through a VPN gateway or route table, routing to a third-party firewall, and then dropping. Azure DNS should show an accurate answer to help the customers, which is its area for improvement."
"The solution’s pricing could be improved."
"The DNSSEC feature is not yet available on the DNS server so it needs to be added."
"The solution lacks scalability."
"Azure DNS' documentation needs to improve."
"The support from Microsoft in India is an area of concern where improvements are required."
"It used to work fine for all the devices, but it started to slow and become non-responsive. I would have to reload the page two or three times before all the pages loaded. With OpenDNS, I only need to load the page once."
"Quad9 could improve by having more free features, such as custom DNS filtering."
 

Pricing and Cost Advice

"I would describe Azure DNS as a cheaply priced product."
"To use Azure DNS, I need to buy the license meant for Windows Server."
"We have an enterprise license agreement with Microsoft. Their pricing is competitive. I would rate it a three and a half out of five."
"We use the tool's free version."
"The solution payment model is based on how many users use it. This is not an expensive solution, but it can depend on how long we use it. However, if the price was decreased it would be helpful."
"The price is low and it's a reasonable price for that product."
"The pricing is expensive."
"In my opinion, DNS is inexpensive. The pricing depends on how you use it, but overall, it's quite affordable. It typically costs just a fesw cents, and Microsoft even offers ten thousand free hits per month."
"The price of Quad9 is free."
