Master Your DNS, DHCP and IPAM

DNSBOX400 is a master appliance for integrated IPAM (IP Address Management), DNS and DHCP. It is a central management server for controlling unlimited remote DNS and DHCP servers and enabling integrated administration by a team of any size, distributed anywhere.

DNSBOX Master - DiagramIt features a carrier-grade fully-featured integrated DDI management application – first released in 1996 and soon adopted by more than half of the world’s top 20 ISPs. Now in its 7th generation, it is embedded on ApplianSys’ world-class appliance platform.

DNSBOX400 (Download factsheet) integrates particularly closely with the ApplianSys DNSBOX200 “slave” DNS / DHCP server, but is also compatible with any other RFC-compliant DNS server.


Use your IP space more efficiently

  • Track IP address space and network resources in real-time
    • Reports on IP / subnet use and allocation
    • Tree-view and other graphical reports on IP space


  • Utilize IPAM tools simplifying IPv4 and IPv6 address planning:
    • Extensive reporting on IP space usage
    • Embedded bitmask calculator
    • Simple subnet-DHCP server binding
    • Simple subnet-zone binding
    • Merge and split subnets on the fly
    • Calculate possible values for new blocks and individual IP addresses
    • Network scanning tools for locating clients, identifying rogue and orphaned IP addresses
    • Customise IPAM information with user defined fields
  • Re-use information from existing spreadsheets and databases using CSV Import/export
  • Script large or complex IPAM tasks via a Command Line Interface
  • Use rich XML-RPC and SOAP APIs to integrate with other systems

Simplify DNS administration

DNSBOX400 automates synchronisation between linked DDI servers – giving you visibility, control, security and easy management all from a single web interface.


DDI deployments make it easy to:

  • Set up secure SSH connections and establish links between servers
  • Centrally manage and control remote DNS and DHCP servers from one interface:
    • Configure easily the same permitted subnets and DNS forwarding rules on all your remote servers
    • Push new firmware on to connected DNSBOX200s
    • Reporting – aggregated performance of all your remote recursive DNS servers

For smaller requirements without integrated IPAM, DNSBOX300 masters can be combined with DNSBOX200 slaves to give you
