Overview
- Dynamic Host Configuration Protocol
- Uses UDP 67 (server) / 68 (client)
Protocol
- Discovery: client broadcast 0.0.0.0 -> 255.255.255.255
- Offer: server response 10.0.0.1 -> 255.255.255.255 ("your IP is 10.0.0.4")
- Request: client "which server selected" broadcast 0.0.0.0 -> 255.255.255.255 (others see it and withdraw)
- Acknowledgement: server->client lease duration, subnet mask, DNS servers, default gateway
- From now on client uses 10.0.0.4 for communication
