# DNSBOX for DHCP by ApplianSys

> DNSBOX is a dedicated, failover-ready DHCP server appliance from ApplianSys. It replaces Windows Server DHCP, ISC DHCPd/KEA and switch/firewall-based DHCP with purpose-built hardware, deployed by organisations in 150+ countries since 2002.

This microsite (dhcp.appliansys.com) is a DHCP-focused counterpart to the main ApplianSys and DNSBOX sites — it covers DNSBOX purely as a standalone DHCP appliance for organisations that don't need full DDI (DNS/DHCP/IPAM), rather than the broader DNSBOX/DDI product line.

## Product pages

- [Home](https://dhcp.appliansys.com/): Landing page introducing DNSBOX as a dedicated DHCP server, framed around the three priorities network managers care about most — failover, a professional-grade admin UI, and on-site (non-cloud) deployment.
- [About DNSBOX for DHCP](https://dhcp.appliansys.com/dnsbox): Core product page for DNSBOX200 as a dedicated, licensable DHCP appliance — summarises failover, on-site deployment and professional-grade administration, with a downloadable factsheet and demo booking.
- [DHCP Failover](https://dhcp.appliansys.com/failover): Explains why DHCP failover has historically been unreliable on Windows Server and ISC DHCPd/KEA, and how DNSBOX200 failover pairs share configuration and lease data in Active-Active or Active-Passive modes, configurable in a few clicks.
- [Professional UI](https://dhcp.appliansys.com/pro-ui): Details DNSBOX's DHCP administration interface — templates and wizards for common tasks, simplified navigation, built-in configuration validation, and live DHCP statistics — illustrated with a Footprint Center (Phoenix Suns arena) case study.
- [On-site DHCP server](https://dhcp.appliansys.com/on-site): Makes the case for keeping DHCP on-premises during cloud migrations, since DHCP isn't supported on platforms like Azure or AWS — positions DNSBOX as a cost-effective on-site alternative with HA pairing, illustrated with a Georgia State Treasury case study.
- [Central Management](https://dhcp.appliansys.com/central-mgmt): Describes DNSBOX Central Management — secure, SSH-tunnelled remote access to a fleet of DHCP appliances with no VPNs or open firewall ports required, plus fleet-wide lease visibility — illustrated with a GE Appliances manufacturing-plant case study.

## Customer evidence

- [Success Stories](https://dhcp.appliansys.com/evidence): Directory of 30+ customer case studies across education, government, healthcare, manufacturing, legal and large-venue sectors, covering DNSBOX deployments for Windows Server replacement, cloud migration, HA failover and licence cost savings.

## Optional

- [DHCP for large venues guide](https://dhcp.appliansys.com/knowledge-base/guide-dhcp-large-venues): Comprehensive guide covering failover, DHCP relay, lease times and scalability for high-density venue deployments.
- [ISC KEA vs DHCPd](https://dhcp.appliansys.com/isc-kea-server): Comparison of the DHCP engines (ISC KEA and ISC DHCPd) available within DNSBOX, and why a relational-database-backed engine matters for Active-Active failover.
