Netpractice: 42 Tutorial

: Levels later in the project will use masks like /26 , /27 , or /29 .

Example: Left host: 192.168.1.10/24 gateway 192.168.1.1 Right host: 192.168.2.10/24 gateway 192.168.2.1

0.0.0.0/0 means "any IP not found in my table." netpractice 42 tutorial

The on a host computer must match the exact IP address of the router interface connected to that host's local network.

Look closely at the router; it will have two interfaces (e.g., R1-A and R1-B ). Devices on side A must list R1-A as their gateway. Devices on side B must list R1-B as their gateway. Ensure 0.0.0.0/0 routes point to the correct internal gateway interface. Levels 7 - 8: Multiple Routers and Inter-router Subnets : Levels later in the project will use

A packet traversing from Client A to a distant Server B needs explicit instructions at every intersection. Check the routing tables of the intermediate routers. If Router 1 receives a packet meant for Server B, Router 1's routing table must have a rule directing that traffic to Router 2's adjacent interface. Levels 9 - 10: Internet Gateways and Overlapping Subnets

: Most students fail because they forgot to set the default gateway on a computer. Devices on side A must list R1-A as their gateway

Look at the diagram and count how many distinct subnets exist. A new network is created by every interface of a router.
