Before you touch the levels, you need to understand three key "rules of the road." 1. The IPv4 Address and the Mask

Make sure two or more devices on the same switch can talk to each other.

You will often see IPs written like 192.168.1.1/24 . The /24 indicates how many bits are set to 1 in the mask.

If the destination IP is outside the local subnet, the host checks its routing table for a matching rule. The Default Route ( 0.0.0.0/0 ) netpractice 42 tutorial

Before attempting the levels, you must master three fundamental concepts: Binary conversion, Subnet Masking, and Routing Tables. 1. IP Addresses and Binary Conversion

Take your time, draw diagrams, and remember: even the hardest level is just multiple small, simple networks chained together.

Displays whether packets are traveling correctly. Before you touch the levels, you need to

Is the IP address identical to the Broadcast Address? (Invalid)

In the final levels, you will deal with multiple routers. You may need to add manual routes to the routing tables to tell router A how to reach a network behind router B.

Two routers connected directly – only 2 usable IPs. The /24 indicates how many bits are set to 1 in the mask

: A 32-bit address (e.g., 192.168.1.1 ) split into a network part and a host part .

These levels focus on direct communication. You’ll typically see two clients (A and B) that can’t talk.
