IP, DNS, and DHCP Basics for Tech+
Short answer
Tech+ wants simple recognition of these core terms. IP address - A numeric address used to identify a device on a network. DHCP - A service that automatically assigns IP addresses to devices. DNS - A service that translates names (like websites) into IP addresses. Simple scenario logic: - Device can't get online and has no IP -> DHCP issue (at high level). - Website name doesn't resolve but internet works -> DNS issue (at high level). Out of scope: manual IP configuration steps, DNS record types, subnet masks/CIDR math.
