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

"Azure DNS is a user-friendly and very easy-to-manage solution."
"The integration with other services on Azure is valuable."
"The initial setup is straightforward and not that complex."
"The setup is relatively straightforward."
"The most valuable feature of the solution is that it is a stable product."
"Azure DNS provides end-to-end P2P connectivity and enhances security, making it more secure and reliable."
"The best feature is the domain register, and whenever you create any resources, Azure DNS will automatically create a record for you."
"From a security perspective, Microsoft is much better than other cloud providers."
"Setting up Quad9 is straightforward if you know what you're doing, and it's easy to use overall."
"The most valuable feature of Quad9 is that it is a free solution."
 

Cons

"Azure DNS does provide enhanced support for applications and includes several security features to protect against threats. One of the security features it offers is the ability to detect and prevent dangling DNS records, which can be used in cyber attacks. Dangling DNS records occur when a website owner creates a domain name but forgets to remove the CNAME record, leaving the domain vulnerable to takeover by malicious actors. Azure DNS includes security measures to identify and prevent such threats, helping to keep your DNS infrastructure secure. However, if Microsoft could add more security capabilities to the DNS, that would be great to detect and identify anomalies that are happening to prevent cyber threats."
"There are some issues with the solution's performance where improvements are needed."
"What needs improvement in Azure DNS is visibility in terms of troubleshooting."
"Azure DNS could improve by having more updates."
"The process of creating a virtual mission could be improved."
"The initial setup of this solution could be less complex and require less manual configurations."
"The CDN integration could be improved."
"I did not see any improvements required."
"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 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."
"Azure DNS is a cheap solution, and I rate it a two out of ten for pricing."
"The solution is moderately priced."
"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 itself is free but you need to pay for the Microsoft Azure infrastructure and host your domains in Azure to use it."
"The solution's price is reasonable."
"The price is low and it's a reasonable price for that product."
"The price of Quad9 is free."
