Domain Name System (DNS)

Domain Name System (DNS)2019-07-08T10:59:54-05:00

The naming system for computers and computing services on a network. The DNS connects common name expressions to the numerical address of the network device. DNS ensures that email data is routed to the appropriate email servers and web traffic is routed to web servers, for example.

Because DNS is at the very core of IP traffic, Cisco incorporates aspects of its framework to analyze and mitigate harmful network activity on a business’ internal network. See Cisco Umbrella.
