How do Wake-On-Lan works?
Summary
The article provides a practical overview of Wake-On-LAN, detailing how a Magic Packet is formed (six 0xFF bytes followed by the MAC address repeated 16 times) and how to send it over UDP. It discusses limitations (requires Ethernet, same network/VLAN, no guaranteed delivery) and includes a Golang implementation example with CreateMagicPacket and SendMagicPacket, plus a link to a GitHub project.
