Port 11434 — ollama

Dev and ops

Port 11434 carries Ollama over TCP. Above 1023, so an ordinary user can open it.

1024–49151. Meant to be applied for, though some numbers here are custom by habit.

By custom · Not a registered number but one settled by habit. Another program may well have taken it first.

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.
