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

"The tool is easy to manage and use."
"I like the feature where I can add multiple DNS records for the same subdomain."
"Azure DNS provides end-to-end P2P connectivity and enhances security, making it more secure and reliable."
"From a security perspective, Microsoft is much better than other cloud providers."
"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."
"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."
"The setup is relatively straightforward."
"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 process of creating a virtual mission could be improved."
"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 security features and stability needs to be bettered."
"The CDN integration could be improved."
"Azure needs to add domain registration to the DNS service."
"The solution’s pricing could be improved."
"There are issues with the cloud systems."
"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

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