  title: TCP/IP Protocol Suite
  description: Layers and core protocols of the TCP/IP model.
  summary: "The four-layer TCP/IP model with the protocols that live at each layer: application, transport, internet and network access. It is the model the internet actually uses and a compact reference for where a given protocol belongs."
  use_when[2]: You want the simpler four-layer view instead of the seven-layer OSI model.,"You are placing a protocol such as DNS, TCP or ARP in its layer."
  caveats[2]: The layer names are not used identically in every textbook; some split network access into link and physical.,Protocols such as ARP and TLS do not fit one layer cleanly.
