Practical addressing and tools
Apply addressing in real networks.
📖 Key ideas
- DHCP assigns IP, mask, gateway and DNS automatically.
- Static IPs for servers, printers and routers.
- Check settings: ipconfig (Windows), ip a (Linux).
- Test connectivity: ping, traceroute/tracert.
- Document IP plans (IPAM) to avoid conflicts.
💡 Real-life example: DHCP is a hotel reception assigning rooms (IPs) to arriving guests automatically.
