DHCP - liabilityissue/Net-150 GitHub Wiki
Dynamic Host Configuring Protocol
Essentially giving IP addresses, subnet masks, default gateways, and DNS servers.
Similar to ARP and will go through welcome protocol for each time your computer turns on.
DORA - back and forth. Discover, Offer, Request, Acknowledgment
Discover - layer 2-3 broadcast
Offer - layer 2 offering IPs
Request - MAC requesting IP
Acknowledgment - server sends to client as a lease
DHCP can expire if device hasn't been connected in a long time. Expiration dates for DHCP can be set. Helps with redundancy.
