How to read this

  • A port number is 16 bits, so it runs 0 to 65535. There is no port 65536.
  • Opening anything at or below 1023 needs root on Unix.
  • Plain and encrypted often live on different numbers — 80 and 443, for one.
  • Numbers like 3000 and 8080 were never registered; those are marked as custom.
