Improve DNS optimisation with server management services. Use modern DNS, caching, DoH, DoT and SVCB/HTTPS records for faster, more secure websites.
A website’s performance rests on modern-day DNS. The first request to a website means that the user’s browser must connect to the server. DNS has to resolve the domain name. While the tuning and optimization of applications and databases is critical, so is the optimization of DNS.
The Server Management Support team helps clients adopt modern DNS practices to enhance performance, security, and reliability.
An Overview
Why Optimise DNS?
DNS resolution occurs even before the browser establishes a connection to the website. As a result, website visits can be faster on subsequent requests due to local caches and modern DNS features.
DNS over TLS (DoT) and DNS over HTTPS (DoH)
The main purpose of both DoT and DoH is security. Confusingly, both aim to provide protection for DNS requests. Information can be somewhat faster on return visits if DNS requests are protected.
DNS security, combined with modern fast recursive resolvers and proper local caches, can be a win-win for websites.

SVCB and HTTPS DNS Records
SVCB and HTTPS resource records give authoritative DNS servers the ability to communicate to the client the information about the available endpoints and the supported protocols. Clients can then make a connection to the highest supported version. Services can benefit from SVCB and HTTPS records.
Some clients are non-supporting. For any implementation, be sure to test records across multiple environments and clients.
DNS Caching Best Practices
DNS caching keeps frequently accessed records locally to speed up queries, making repeated requests less common and reducing the load on recursive servers. By adjusting positive and negative caching TTLs, you can define an appropriate balance between speeding up responses and allowing DNS changes to propagate throughout the system.
Before deployment, test the behavior of new cache configurations to eliminate possible issues.
Key Considerations
-
- Currently, the most efficient DNS providers are those that employ the latest standards.
- DNS over HTTPS (DoH) should be used where available.
- DNSSEC should be tested before deployment.
- SVCB and HTTPS records should be verified across multiple clients and in multiple environments
- After deployment, performance should be monitored and assessed on a regular basis.
Conclusion
Optimizing DNS along with application and infrastructure tuning helps improve the early stage of client connectivity. You can achieve this through effective caching, encrypted DNS, and modern DNS record types.
Our deep understanding of industry best practices, paired with the reliability and practicality of our configurations, makes it easy to create the most effective DNS infrastructure for Bobcares customers.
