Domain Name System (DNS)
Discuss how DNS translates domain names into IP addresses and the hierarchical structure of domain names.
Internet Protocol (IP)
IPv4 vs. IPv6
Compare IPv4 and IPv6 addressing schemes and the transition to IPv6.
Routing
Explain how routers direct data packets to their destinations using routing tables and algorithms.
Security
Firewalls
Discuss the role of firewalls in protecting networks from unauthorized access.
