CompTIA Network+

Master the addressing and routing skills at the heart of every network you will ever work on. Through the industry-proven lens of the CompTIA Network+ (N10-009) exam, this course starts with TCP/IP addressing from the ground up, including binary math, subnet masks, and CIDR subnetting, then explains how routers work, NAT, port forwarding, and the major dynamic routing protocols: OSPF, BGP, EIGRP, and FHRP. Multiple subnetting scenarios build real fluency rather than memorized formulas, and online labs reinforce IP configuration and routing tasks. Not planning to take the exam? IP addressing and routing are skills network professionals use every day, so they apply on the job whether or not you pursue the certification. You'll understand how packets travel across networks and how to configure and troubleshoot addressing. The first module is designed as an accessible entry point, and expert instruction with practical examples helps you build confidence step by step. You'll finish able to subnet networks and explain how routers move traffic between them.

Learn the protocols, services, and security mechanisms that run on top of TCP/IP. Through the industry-proven lens of the CompTIA Network+ (N10-009) exam, you'll move across four modules from core protocols such as TCP, UDP, and ICMP and everyday diagnostic tools, through application services including DNS, DHCP, NTP, email, file transfer, and remote access with SSH, to the access control, encryption, and PKI that protect it all. Wireshark packet capture and hands-on online labs, including configuring a DHCP scope and creating DNS records, help you set up and secure the services users depend on every day. Not planning to take the exam? These services run in every organization, so the skills apply on the job whether or not you pursue the certification. You'll see how network services work and how to troubleshoot them when they fail. The first module is designed as an accessible entry point, and each module builds on the last so you gain the full knowledge stack that runs on top of TCP/IP.

Build the foundational networking skills and physical layer knowledge that underpin all network communications. Through the industry-proven lens of the CompTIA Network+ (N10-009) exam, this course builds the vocabulary every network professional needs: the OSI and TCP/IP models, frames and MAC addresses, topologies, cabling standards, Ethernet, and structured cabling. You'll learn how data flows through networks, how physical media and connectors are selected and installed, and how to track down cabling problems. Online labs reinforce physical installation and cable identification. Not planning to take the exam? The skills still apply on the job. Whether you support a small office network or simply want to understand how networks really work, this course gives you a practical foundation you can use right away. Clear, expert instruction makes each concept approachable, and the first module is designed as an accessible entry point, so you can start with confidence even if networking is new to you.

Build the advanced LAN and wide-area network skills that enterprise networks depend on. Through the industry-proven lens of the CompTIA Network+ (N10-009) exam, you'll start with switch management, VLANs, inter-VLAN routing, and 802.1Q trunking, then work with Cisco CLI commands, port security, DHCP snooping, dynamic ARP inspection, and IDS versus IPS. From there, you'll explore IPv6 address structure and IPv4-to-IPv6 transition, and finish with WAN connectivity, including MPLS, Metro Ethernet, broadband, satellite and cellular networking, and VPNs. Online labs reinforce switch configuration and VLAN tasks. Switch CLI practice and network device placement scenarios show how each piece fits together in a real network. Each module builds on the last, and the first module is designed as an accessible entry point. Expert instruction keeps each topic practical. Not planning to take the exam? Switching, IPv6, and WAN skills connect your local network to everything else, and they apply on the job whether or not you pursue the certification.

Explore the technologies that define how modern networks are designed, deployed, and operated. Through the industry-proven lens of the CompTIA Network+ (N10-009) exam, you'll cover the 802.11 standard family, frequency bands, channel planning, and wireless security from WEP through WPA3, then move into virtualization and cloud computing (IaaS, PaaS, and SaaS), software-defined networking, and data centers. You'll also examine IoT and IIoT, ICS and SCADA systems, and network operations practices such as configuration management, documentation, change management, patching, and disaster recovery. Online labs include AWS cloud exploration, SDN components, and network documentation. Not planning to take the exam? Modern networks run on wireless, virtualization, and cloud, so these skills apply on the job whether or not you pursue the certification. Wireless design and installation scenarios help you plan and troubleshoot with confidence, and the first module is designed as an accessible entry point. Expert instruction keeps every topic practical, so you can see how the pieces of a modern network fit together.
