TrustRadius Insights for F5 BIG-IP DNS are summaries of user sentiment data from TrustRadius reviews and, when necessary, third party data sources.
Pros
Customization Flexibility: Users have appreciated the ability to customize the load balancing solution according to their specific requirements, allowing for tailored configurations that meet their unique workload demands effectively. For example, users have mentioned creating custom rules and policies to optimize traffic distribution based on their application needs.
System Stability: Reviewers consistently emphasize the system's reliability, noting its robust performance in maintaining stable operations even during high traffic periods or under challenging conditions. Some users have highlighted instances where the system continued to function seamlessly without disruptions during peak usage times.
DNS Express Feature Benefit: Customers found the DNS Express feature invaluable in enhancing response times by efficiently caching entries, resulting in faster and more responsive domain name resolution for optimized user experiences. This feature has been particularly praised for reducing latency and improving overall network efficiency across different deployment scenarios.
It helps us complete a lot of the specific tasks, we have low balance surgeries you guys offer and stuff like that as well, as well as web application firewalls. It helps us with our daily tasks and things like that.
Pros
I would say the load balancers. I think the load balancer service is pretty good.
Cons
I don't have any areas of improvement. I'm pretty satisfied with the product so far.
Likelihood to Recommend
I don't have any scenarios off the top right now that I can mention.

Today we use it for Global Availability and HA across our multiple cloud regions and equinix facilities both internally and externally.
Pros
Being able to create topology load balancing is very easy and straightforward
It works really well to detect which region or state you are in to be able to load balance to the closest location
Cons
We struggle with the fact that F5 BIG-IP DNS uses the LDNS. Today we use infoblox and we are able to tag ECS data so that the F5 can see the true source of the client but it would be cool if somehow that would work without having to forward.
One thing that I also struggle with is the time stamps and adding new GTMS into the cluster. I have wiped out my deployment before because the timestamps we're wrong.
Likelihood to Recommend
I would recommend it in a heartbeat. Everything I have done with F5 BIG-IP DNS has been easy. Adding F5 BIG-IP DNS to the server groups and automatically detecting LTM VIPs is so easy and works like a charm. Creating wide IPs is simple and effective.

We use F5 BIG-IP DNS for DNS resolutions. We used to have Infoblox for DNS queries and with Infoblox as our environment grew, there were resource issues. We had users complaining about DNS queries taking lot of time. With Infoblox, service used to restart nightly at 10pm. When we moved to F5 BIG-IP DNS, nightly restart was addressed.
Pros
DNS Caching
DNS Response Time
Stability
Cons
Instead of purchasing separate DNS appliance, would like to see a containerized LTM with DNS
Likelihood to Recommend
F5 BIG-IP DNS provides quicker response time to queries.
We use it to distribute traffic between our Data Centers globally and we use it to monitor applications for a DR scenario. It allows our applications teams to deploy their applications wherever they want without having to worry about updating DNS.
Pros
Monitoring
Easy to use
Cons
Automation
Make it so you can get to the pool from the WIP page
We have GTMs located in 2 different distributed data centers in the Midwest and Western US. F5 GTMs have allowed us to run active-active and active-passive applications for many years. This achieves our goal of resiliency and allows us to make major changes in one DC without affecting customer traffic.
Pros
Active-active applications
Resiliency
Performance
Maintenance
Cons
More advanced monitors
Likelihood to Recommend
A great product for a company to create their own cloud services as well as delegate zones to offload from other DNS applications.
In order to be able to provide DNS service, hope to see more DNS specific features. So far it still can be achieved via iRules, however, it still consumes resources
F5 BIG-IP DNS is the perfect solution to efficiently stop DNS-related attacks and distribute user traffic intelligently to multiple service-consumption points. With its tight integration with the local traffic management capabilities of BIG-IP LTM, it becomes super easy to direct excess traffic during peak usage periods to places such as a pay-as-you-go cloud (cloud bursting) so that user experience can always remain at its best! With its many implementation options, such as Intelligent DNS resolution (GSLB with WideIP), and Accelerated DNS resolution (DNS Express for Authoritative Answers, hardware-accelerated DNSSec, LDNS caching resolver) it offers flexibility and simplicity to integrate performance and security to any DNS environment.
Pros
Direct clients to the best possible app experience
Secure DNS infrastructure against attacks, including DDoS
Easily integrates into any environment
Cons
I'd like to see better reporting capabilities on the decision-making process for DNS resolutions. Currently there are plenty of log messages for that, but I'd like to see tighter integration into the GUI.
It could be an improvement to better discriminate features intended for AA vs LDNS functionality within the GUI.
Likelihood to Recommend
F5 BIG-IP DNS is well-suited for any organization looking to improve their Authoritative and Local DNS security and performance capabilities.
