enterprise DNS

Contributor(s): Jim Williams

Enterprise DNS is an enterprise-class implementation of the domain name system (DNS) that resolves external and internal queries for large organizations in a centrally managed, scalable, automatable and secure way. It can be defined as both a state of mature DNS architecture within an organization as well as the sophisticated DNS structure itself.

Consisting of a purposefully-architected system of relationships between DNS servers, resolvers and network clients, enterprise DNS centralizes DNS management and monitoring. This approach to DNS architecture provides complete network visibility, minimal operational effort, simplified self-service provisioning, higher-level automation and a reduction of errors or security issues.

Unlike DNS for a single device user, corporate DNS systems can become overly complicated with hundreds of overlapping entities that need to be constantly updated. This can make management and the ability to scale difficult, leading most organizations to patch over issues with upgrades rather than use a comprehensive, proactive approach. Even small, momentary misconfigurations of DNS or outages to DNS resolvers can cause large impacts to an organization, making a central solution like enterprise DNS a necessity.

Implementing enterprise DNS is beneficial for organizations where the infrastructure and layers of DNS, DHCP and IPAM have grown too complex, making it hard to manage in a decentralized way and impacting the adoption of new initiatives like cloud, SD-WAN and improved cybersecurity. This typically includes organizations with multiple geographic locations or a constant need for DNS architecture changes. Enterprise DNS creates a foundation for IT infrastructure that enables these organizations to rapidly and reliably consume new technologies, capabilities and configurations to meet flexible business demands.

Uses of Enterprise DNS

In addition to standardizing the delivery platform for DNS services, enterprise DNS also leverages the effort to increase the reliability, flexibility, security and speed of DNS and IT initiatives. A few examples of what the implementation of enterprise DNS systems has enabled are:

  • Managed connection to millions of IoT devices.
  • The ability to spin up and take down tens of thousands of VMs per hour.
  • Thousands of automated DNS configuration changes per hour.
  • Near-immediate threat detection.
  • Granular visibility into the DNS traffic of thousands of employees, machines and branches.
  • A virtualized network for DHCP services across hundreds of locations.
  • Management of millions of IP addresses with 100% uptime.
