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.
Louis Geoffroy - PeerSpot reviewer
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 the solution is that it is a stable product."
"If you're running your enterprise application on Azure, it's convenient to use Azure DNS. It has native integration with other Azure solutions, and Microsoft is a globally recognized DNS provider. You also get CDN services. If you're a media company that requires on-demand data streaming, your DNS plays a vital role by working with CDN services to publish your application. It's cheaper and easier to expand your solution."
"The initial setup is straightforward and not that complex."
"One of the key benefits of Azure DNS is its integration with other Azure services. As it is a solution developed by Microsoft, it is easy to integrate with other Azure offerings. Azure DNS also includes Defender for DNS, a feature that protects against anomalies and threats on the DNS. This added security is provided directly by Microsoft. The integration and security features of Azure DNS make it a valuable option for users of the Azure cloud platform."
"Regarding return on investment for Azure DNS, because of the automatization, there is a big return on investment as it's easy to implement it, and you don't necessarily need the expertise to do that."
"The most valuable feature of Azure DNS is it works automatically after configuration. Additionally, the solution is secure."
"Azure DNS provides value beyond its user-friendly interface and easy learning curve."
"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

"The web interface to manage the solution must be made easier."
"The scalability could improve."
"Domain registration is one of the problems. We need to go to application services or web apps to purchase the domain instead. If that were to be equivalent to AWS's Route 53 that would be good. But, it is not as flexible as that."
"The DNSSEC feature is not yet available on the DNS server so it needs to be added."
"The initial setup of this solution could be less complex and require less manual configurations."
"There are issues with the cloud systems."
"There are some latency issues that could be improved."
"The product must be integrated with additional security features."
"Quad9 could improve by having more free features, such as custom DNS filtering."
"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."
 

Pricing and Cost Advice

"The solution is free."
"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."
"We have an enterprise license agreement with Microsoft. Their pricing is competitive. I would rate it a three and a half out of five."
"To use Azure DNS, I need to buy the license meant for Windows Server."
"I would describe Azure DNS as a cheaply priced product."
"The price is low and it's a reasonable price for that product."
"The solution's price is reasonable."
"The price of Quad9 is free."
