A roadmap for networking careers: TCP/IP, routing, switching, wireless, firewalls, cloud networking, and troubleshooting.
Learn how devices communicate through OSI/TCP-IP, IP addressing, subnetting, DNS, DHCP, and troubleshooting tools.
Calculate subnets, CIDR blocks, gateways, NAT, private ranges, and IPv6 basics.
Use ping, traceroute, nslookup, dig, netstat, tcpdump, Wireshark, and logs to find faults.
Understand LANs, VLANs, STP, routing tables, static routing, OSPF, BGP basics, and device configuration.
Configure access ports, trunks, VLANs, STP concepts, and basic campus network segmentation.
Learn static routing, OSPF, BGP concepts, route selection, metrics, and path troubleshooting.
Use Wireshark to investigate DNS, TCP, TLS, or HTTP failure and write a troubleshooting report.
Operate secure networks with firewalls, VPNs, cloud VPCs, load balancers, monitoring, and documentation.
Understand access rules, stateful firewalls, IDS/IPS basics, site-to-site VPNs, and zero-trust concepts.
Design a small company network with IP plan, VLANs, routing, firewall rules, Wireshark evidence, and diagrams.
Use scripts, lab simulators, documentation, and certification-style practice to become operationally sharp.
Automate inventory, configuration checks, backups, and validation with Python, APIs, Netmiko, or Ansible.
Build labs for VLANs, OSPF, NAT, ACLs, DHCP, DNS, VPNs, and troubleshooting evidence.
