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 an enterprise-grade fully-featured integrated DDI management application – first released in 1996 and now in its 7th generation – embedded on ApplianSys’ world-class appliance platform.

DNSBOX400 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

  • Automated synchronisation of live DNS, DHCP and IPAM data
  • Central dashboard providing:
    • At-a-glance view of subnets, zones and server performance
    • Powerful search tool for DDI data


  • Built in RFC compliant data validation of all entries to DNS and DHCP configuration
  • Automate DNS management process
    • Slave zone creation
    • Zone serial incrementing
    • Reverse entries
    • Validation and consistency checks
    • Pre-filled data entries from templates
  • Centrally monitor DNS and DHCP service performance on all linked servers
  • Command Line Interface for scripting large or complex DNS tasks
  • Support for DNS Views. Administer an unlimited number of discrete copies of the same zone(s)
  • Perform simple bulk data changes, including TTL zone values
  • Support for DNSSEC including wizard for simplified zone signing
  • ENUM support for mapping telephone numbers to IP addresses
  • Support for IPv4 and IPv6 records
  • Support for an unlimited number of remote secondary DNS/DHCP servers
  • Agentless integration with Microsoft DNS and DHCP
  • Push bulk firmware updates to connected remote servers

Control task delegation

  • Built-in local and centralised user authentication
  • Fully granular ‘User Groups’ feature lets an administrator maintain tight control over the rights of delegated users


  • Support for an unlimited number of concurrent administrators
  • Transaction log with audit trail (who, what, when); unlimited undo and redo
  • Host and zones templates can be assigned to individual administrators to simplify host/zone creation


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

  • Central management of DNS services from the DNSBOX300 master
  • Local on-box management of DHCP services from the DNSBOX200
