A new bar will appear at the top. In that bar, change the dropdown Display filter to String, type www.flcc.edu in the search box, and click the Find button. d. Referring to the OSI model, DNS, at Layer 7, is in the UDP datagram at Layer 4. The data is then encapsulated by a Layer 3 IP packet. Finally, the IP packet is encapsulated by a Layer 2 frame. Why do you think DNS uses UDP for DNS queries and replies (aside from responses greater than 512 bytes, which are rare, and a zone transfer, which is when a primary DNS server sends a copy of its zone containing DNS records to a secondary DNS server for that domain, which both use TCP)? Note A zone is part of the DNS namespace under the management and administration of a single organization. A zone can consist of more than one subdomain, and different zones can exist on the same DNS server.
