Domain Name Service (DNS) Server

Host devices on the same network have unique IP address numbers, but a common part of the address is shared by all hosts on the same domain (e.g., yourdomain.com). These numbers can be difficult to remember, so each host is usually assigned a host name to serve as an "alias" for its IP address. A DNS server translates these host names back into IP addresses that can be understood on the network.

For example, if an In-Sight sensor with the IP address 192.168.1.2 is named "PRODUCTION2", the DNS server knows that PRODUCTION2 actually refers to the In-Sight host at the specified address. The DNS Server field determines which host is contacted (by its IP address) to resolve the translation of host names to IP addresses within the specified domain.
