Notes:

Hosts - Any device that sends or receives traffic
Every host needs 4 items for Internet Connectivity:

  • IP Address - Host's identifier on the internet
  • Subnet mask - Size of Host's network
  • Default Gateway - Router's IP Address
  • DNS Server's IP - Translates domain names to IP Adresses

LAN - Local Area Network

WAN - Wide Area Network
-> Connects separate LANs together

IP (Internet Protocol)
Dictates how things are delivered and permits optimizing the transfer route

IPv4 - 32bit
IPv6 - 128bit, no backwards compatibility
