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 most valuable feature is the ease of installation."
"The DNS resolution is the most valuable feature."
"Can be configured to achieve a hundred percent reliability"
"The best feature is the domain register. The other great feature is that whenever you create any resources, Azure DNS will automatically create a record for you."
"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 solution allows you to host DNS service without using Azure's servers."
"Data protection is paramount across cloud platforms"
"It is a very stable solution."
"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

"The scalability could improve."
"Azure DNS sticks mostly with the Azure native solution and doesn't scale well in a multi-cloud or hybrid environment."
"The CDN integration could be improved."
"My advice to others is that this is a quick solution that is easy to install, but it is not a highly scalable one."
"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."
"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."
"They should include more integration with other platforms."
"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

"We use the tool's free version."
"The solution is moderately priced."
"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 is free."
"The price is low and it's a reasonable price for that product."
"I would describe Azure DNS as a cheaply priced product."
"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 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 of Quad9 is free."
