The Domain Name System (DNS) is a franchise critical application of every enterprise. It is primarily responsible for translating names to IP addresses so that the network communication takes place between two systems. It has evolved significantly over the past few decades. The ability to modernize the legacy DNS technology and the agility to cater to the most modern technologies such as cloud and microservices requires a management system that can meet such requirements. This is where TCPWave excels. The TCPWave DNS remotes, which are managed by the TCPWave DDI controller, provide seamless agility by providing a 100% SLA (Service Level Agreement) in the most complex networks of today's enterprises. Changes performed on the TCPWave DDI controller are reflected immediately on the remote TCPWave DDI appliances. Changes can also be scheduled for a future time. TCPWave DNS is resilient to network outages. It can automatically query the upstream authoritative sources and respond without any service interruption. TCPWave is the only provider to offer a technology for converting a recursive cache-only DNS resolver into a standalone emergency master when a wide area network blackout is experienced. TCPWave is also the only provider to provide a CNAME flattening technology to its customers. Finally, TCPWave is the only provider to strip out DNS poisons and taints from the responses received from the third party delegations that can potentially poison the internal recursive caches of an enterprise.
