Two or more SolidDNS™ systems may be deployed within the network as both primary and secondary DNS servers, allowing for additional security and redundancy of DNS data. They may be used to resolve local hostnames to private IP addresses or to resolve external domains on the Internet. They can also replace or complement an existing DNS server.

The SolidDNS™ appliances can also provide full DHCP services to network clients.

The diagram shows two SolidDNS™ appliances configured as a primary and a secondary DNS server for a small network. This deployment results in faster DNS response times for queries from the internal network as well as better security and redundancy of DNS data.
