🏷️ DHCP Is the Receptionist Who Hands Out Name Tags
DHCP is the receptionist who hands out name tags for the network. When devices join, DHCP gives them an IP address, subnet mask, gateway, DNS server, and lease time. This ELI5 networking guide explains automatic network configuration, DHCP pools, reservations, and common problems like full pools or rogue DHCP servers.
🏘️ Subnets Are Neighborhoods with Boundaries
Subnets are neighborhoods with boundaries. Devices in the same subnet can often communicate locally, while devices outside the subnet need a router. This ELI5 networking guide explains subnet ranges, subnet masks, gateways, and common subnet problems using a simple neighborhood metaphor.
🚦 Routers Are Traffic Cops for Packets
Routers are traffic cops for packets. They help data move from one network to another by choosing the next hop toward the destination. This ELI5 networking guide explains routing, default gateways, routing tables, and common problems that happen when packets get sent the wrong way or cannot find their way back.
