TCPWave is the first and only DNS service provider to offer an advanced DNS appliance with advanced features listed below. Our two flavors of DNS share a common SNMP (Simple Network Management Protocol) MIB to provide fault and performance statistics. Our devices running in a recursive cache only mode can become standalone emergency masters to serve the clients when there is a wide area network outage. Our success story is shared by our customers running our DNS appliances on their global internal corporate network. By pre-fetching the IP addresses, the TCPWave cache appliance can reply to the DNS requests immediately, without having the delay of a recursive DNS lookup. This method is extremely valuable in low latency trading environments. Additionally, the Dell TCPWave appliance uses the fastest operating system available, a hardened Linux kernel.
