Architecture Optimisation | Carrier Grade DNS
TruTeq Carrier Grade DNS
The Domain Name System (DNS) is an absolutely critical component of any TCP/IP network. DNS translates human-readable domain names into these machine-readable IP addresses, allowing clients and services to locate and communicate with each other seamlessly.
This is not just a matter of user convenience, DNS supports a more efficient and reliable network infrastructure, enabling content delivery networks (CDNs), load-balancing, simplified network management and the ability to make architecture changes that remain transparent to clients and services.
