Every site served locally. Every site managed from one console

Almost every service is moving to the cloud, but DHCP still has to be served on site. DNSBOX takes DHCP and DNS off Windows and onto dedicated, low-cost appliances, one at each site and sized to it. You manage the whole estate from a single view, and hub-and-spoke failover protects every site without a redundant pair at each one.

One view across every site, whichever appliance is serving

Central management is provided by DNSBOX400. Changes are made centrally on the DNSBOX400 and pushed automatically to the appliances in the field. Each site keeps serving its own leases locally, so day-to-day DHCP never depends on the WAN.

• One console for the whole estate. See subnets, lease use and configuration on every appliance in one place.
• Central changes, local serving. Make a change once and it applies everywhere.
• Secure remote access. Access appliances without exposing them to the internet.
• Delegated administration with a full audit trail. Share day-to-day work with site or regional teams while keeping central control.
• No Active Directory dependency. Work with on premises AD or Entra ID.
• Minimal patching scoped only to DHCP. No DC dependency, no licences for features you don't need.

Failover for every site, without doubling the appliance count

A redundant pair at every site is expensive, and small sites rarely justify one. With hub-and-spoke, one heavier-duty hub backs every low-cost site appliance in its region at once. If any site appliance becomes unavailable, the hub takes over serving DHCP for that site within seconds.

One console for the whole estate. See subnets, lease use and configuration on every appliance in one place. Central changes, local serving. Make a change once and it applies everywhere. Leases are still issued on site. Secure remote access. Reach every unit over an encrypted connection without opening inbound firewall ports, so you avoid a site visit and avoid widening your attack surface. Delegated administration with a full audit trail. Share day-to-day work with site or regional teams while keeping central control. No Active Directory dependency. The design holds whether AD stays on premises or moves to Entra ID, so a cloud migration never strands DHCP. Nothing to patch underneath. No Windows server, database or agents to maintain, which removes a large attack surface around a narrow but critical service.

Chosen by organisations in every sector, from school districts and universities to enterprises and the public sector, running dozens of sites with small central teams. Customers commonly run one DNSBOX deployment for ten years or more, through low-cost hardware refreshes with no migration.
