Improving Precision and Performance for VoIP Service with GeoDNS


In the fast-paced world of Voice over Internet Protocol (VoIP) services, a reliable and swift DNS (Domain Name System) is the backbone that ensures seamless communication. Recognizing the critical importance of DNS, an Australian VoIP provider approached ClouDNS at the end of 2018, seeking a dynamic solution to enhance their services.

VoIP is a technology that is heavily dependent on speed, reliability, and constant uptime. Therefore, it demands a DNS hosting provider that could meet these strict requirements. In this case study, we dive into the challenges faced by our client and how ClouDNS managed to help and support their remarkable growth.


In 2018, our client, a prominent VoIP provider in Australia, faced a critical decision point. They were standing at a crossroads, dealing with multiple options and unsure about which path to take. The future of their business hung in the balance, and the stakes were high.

Their search for a new DNS service provider originated from the necessity to improve GeoDNS capabilities. The client explicitly expressed the need to direct users to the right country based on their IP address, a crucial feature to optimize service quality.

The Australian VoIP provider had encountered several challenges with their previous DNS service provider. Despite offering a similar service, the provider was rather expensive and could not provide the accurate precision needed for GeoDNS targeting in Australia. Furthermore, the absence of a redundant Anycast network resulted in prolonged DNS query responses, which is a significant drawback for a VoIP provider striving for speed and constant uptime.

Competing in a market demanding high speed and reliability, the client faced the challenge of maintaining competitive prices while providing top-notch services. The existing infrastructure costs were proving to be a barrier to growth, prompting the search for a more efficient DNS solution.
