Network
Every listening port on the machine, the address it is bound to, and a plain sentence when one is open to your whole network.
Every port, not just yours#
Where Servers is filtered, Network is complete: every listening port on the machine, the process behind it, and a dev tag on the ones Pip recognises as yours. If you are trying to work out what has taken port 5432, this is the tool.
This machine, or all interfaces#
The right-hand column is the one that matters. It reads the bind address and translates it into who can actually reach the port:
- This machine
- Bound to loopback (
127.0.0.1). Nothing outside this computer can connect, and that is the safe default most dev servers ship with. - All interfaces
- Bound to
0.0.0.0— anything that can route to your machine and get past the firewall can reach it. Usually deliberate. Occasionally a--hostflag somebody added last Tuesday.
Show exposed only filters the list down to the second kind. It is a good thing to glance at before joining a conference network or a café hotspot.
How current it is#
The list refreshes every 5 seconds along with the rest of the scan, so a port that opens while the window is on screen appears without you reloading anything.
