How Are Computers Named Physically

• The physical way to name computers is to use an Internet protocol address, or IP address

  • spiff.cs.washington.edu’s IP address is: 128.95.1.207
  • cs.washington.edu’s IP address: 128.95.1.4
  • washington.edu’s IP address: 140.142.15.163

• The domain name system (DNS) associates human readable names with the physical IP addresses for use by the computers and routers of the Internet
