Abstract

Examples relate to collecting domain name system traffic. In one example, a computing device may: receive, from a first intermediary network device, a DNS query packet that was sent by a client computing device operating on a private network, the DNS query packet specifying i) a query domain name, and ii) a source address that specifies the client computing device; store, in a data storage device, a query record specifying the query domain name and the source address specified by the DNS query packet; receive, from a second intermediary network device, a DNS response packet; determine that the DNS response packet specifies a response domain name that matches the query domain name; in response to the determination, extract, from the DNS response packet, a resolved address that corresponds to the response domain name; and store, in the query record, the resolved address specified by the DNS response packet.
