4-NetPractice Core Focus: Network architecture, IP subnetting, and system routing logic. Technical Highlights: Configured small network interfaces by resolving connectivity issues between hosts, switches, and internet gateways. Handled low-level networking parameters including IPv4 addressing, subnet masking (CIDR notation), and routing metrics. Diagnosed and repaired routing tables to ensure efficient and valid data packet transmission across subnet boundaries. Masteted foundational networking concepts (NAT, public/private addressing) to ensure logical infrastructure coherence.
