The video tutorial covers DHCP and DNS, both application layer protocols operating over UDP. DHCP assigns network parameters like IP addresses, while DNS resolves domain names to IP addresses. The tutorial explains the DNS process, involving a single UDP request and response, and describes the roles of DNS servers, root name servers, and authoritative name servers. It also discusses various DNS records, such as A and TXT records, and concludes with a deeper understanding of DNS and DHCP functionalities.
