Ultra-secure, High Performance DNS/DHCP Server

DNSBOX200 is an advanced DNS slave, recursive resolver (DNS cache) and DHCP server for high performance and security needs. It is a very flexible appliance, which can be licenced for whichever of the 3 services you need and adapts to the specific role(s) to give you a fit-for-purpose device.

DNSBOX-Slave-diagram2 It can be deployed in different ways:

  • Managed seamlessly from the DNSBOX400 / DNSBOX300 master web interface
  • Linked to other DNS or DHCP servers
  • As a standalone server (DNS cache or DHCP)

In addition, DNSBOX200 can be used as a DNS master, for editing authoritative DNS records.

 

DNSBOX200 runs authoritative and recursive (cache) DNS as separate services on the same physical server. This:

  • Improves security by isolating the authoritative server from the more vulnerable DNS cache
  • Means you can follow this best practice approach yet only need to pay for and manage one physical server – the best of both worlds
  • Gives you better performance as specialised software is used for the individual services:
    • BIND for authoritative
    • Unbound for recursive

When you use the authoritative resolver as a DNS slave…

  • You have the specialist DNS admin features you need on a slave:
    • Ability to display, filter and search for zones, as well as view their status
    • Real-time and historical graphs on performance of your DNS service
    • Easy monitoring of slaved zones
    • Support for slave and stub zones
    • IPv6 support

  • Additional features make the service even more secure and reliable:
    • Support for DNSSEC signed zones
    • TSIG Keys
    • IP-secured connections with other DNS servers
    • Offline master mode – serving zones from their last known ‘good’ state

When you use the recursive resolver (DNS cache)…

  • Because the server is Unbound, you get a more secure solution and carrier-grade caching performance – 2.5x performance of BIND
  • You have the specialist DNS admin features you need:
    • Ability to display, filter, add, edit, delete and search for forward zones
    • Automatic forward zones creation for local zones
    • Real-time and historical graphs on performance of your DNS service
    • Logging recursive queries to syslog and local log
    • IPv6 support

d200-recurs-slave-small

  • Additional features make the service even more secure and reliable:
    • Cache poisoning protection
    • DDoS attacks protection
    • DNSSEC validation
    • High availability load balanced clustering

When you use the DHCP Server…

  • DHCP configuration is easy and accurate
    • Automated validation of DHCP configurations
    • Custom configuration fields
    • Import/export option for easy backups and ability to copy changes between servers
    • Ability to group hosts, subnets and networks
    • Support for all DHCPD options
    • Ability to assign static IP addresses to clients using MAC authentication
    • Automated log rotation
    • IPv6 and DHCPv6 support

d200-dhcp-small

  • You can easily set up DHCP failover to ensure maximum availability
    • Single web interface for managing all failover units
    • Only the primary needs to be configured
    • Automated replication of changes to a secondary active unit
  • Informative DHCP statistics give you full visibility of the service. You can:
    • View and search for leases
    • View and search for hosts, zones, subnets and IP ranges
    • Group subnets
    • Store additional information about devices

If you have just a few small zones, you can use DNSBOX200 as a DNS master for editing authoritative DNS records simply by switching its operating mode from slave to master.

    • Ability to display, add, delete, edit, filter and search for zones, as well as view their status
    • Real-time and historical graphs on performance of your DNS service
    • Easy monitoring of slaved zones
