DNS Disaster Recovery

When a wide area network blackout takes place because of a disaster or an ISP failure a TCPWave DNS cache appliance takes charge as an emergency authoritative appliance interrupting the enterprise's network.

Dual DNS

ISC's BIND, Unbound, and NSD are three DNS flavors with different source code which come preloaded with TCPWave remote appliance package. Once they are configured, they work in sync to enable you with continuous DNS operations.

Stealth DNS Master

Stealth DNS Master keeps your master DNS appliance hidden from the DNS infrastructure. The authoritative DNS appliances that are visible on the network would function as DNS Slaves. A stealth master protects your DNS Data since the slave DNS zones are not writable.

Master-Slave

The authoritative appliances can be configured as a master or as DNS slave appliances. With this topology, TCPWave provides you with high availability where a single DNS zone is served using multiple authoritative DNS appliances.
