Use switches for local connectivity, routers for separating networks.

A router interface must have an IP address that belongs to the subnet it is connected to.

Example: Router A ↔ Router B: A: 10.0.0.1/30 → B: 10.0.0.2/30

Look at the switches. Every device connected to a single switch forms one unique network. Identify which interfaces belong to this group and define their boundaries using your CIDR knowledge. Step 2: Check for Overlaps

Every subnet reserves two addresses that you assign to a device interface:

You might not receive the entire request at once. You must buffer the data until a complete request (marked by \r\n\r\n ) is received. Parsing: Identify the HTTP method, URI, and headers. Step 5: Generating Responses

: A 32-bit unique identifier for a device on a network.

NetPractice is a crucial stepping stone at 42. By completing it, you gain a practical understanding of how web servers operate, which is essential for later projects like Webserv . Focus on understanding the and parsing HTTP requests , and follow the subject specifications meticulously. If you're stuck, I can help by: Explaining how to use select for multiple clients. Going over how to structure your parsing logic. Discussing how to debug telnet connection issues. Let me know which part you'd like to dive into next. Share public link

Look at the routers. A router must have an interface inside every network it connects to.

Alice stared at the message, trying to make sense of it. She quickly opened the NetPractice simulator on her computer and began to configure the routers.

Having a quick reference of CIDR notations and their corresponding subnet masks saves time. For example: /24 = 255.255.255.0 (256 addresses, 254 usable), /26 = 255.255.255.192 (64 addresses, 62 usable).

The IP address of the next router's interface along the path. The Default Route ( 0.0.0.0/0 )
