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.
 |
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

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