## What is Visual TCPIP Trainer?

Visual TCP/IP Trainer turns abstract networking concepts into something you can actually see. Watch packets travel hop by hop across an interactive topology, inspect every frame, and finally understand what really happens between two devices on a network.

Key features
• Interactive topology with PCs, switches, and routers
• Hop-by-hop packet animation with source/destination MAC and IP, TTL, and frame type
• Live ARP tables and routing tables that update as traffic flows
• Editable subnet masks and default gateways so you can experiment in seconds
• Realistic failure modes: misconfigurations, dropped packets, and routing loops

Certification mode (CCNA / CCNP)
• 450 high-quality questions in total: 150 for CCNA, 300 for CCNP
• Organized by domain (IP addressing, routing, switching, security, automation, and more)
• Customizable difficulty (Easy / Medium / Hard) and question count
• Timed exam mode, weakest-domain analytics, and bookmark review
• Streaks that keep you coming back day after day

Built for
• Beginners who want to truly understand "why packets arrive"
• Engineers preparing seriously for CCNA or CCNP
• Trainers and team leads who need a teaching aid for onboarding
• Anyone who wants to refresh TCP/IP fundamentals on the go

Works fully offline. No ads, no tracking. Learn networking the way it should be taught — by watching it happen.
