Port reference

Well-known ports with service names and transport, filterable.

port	service	transport	notes

about this tool

A filterable table of common TCP/UDP services. Type a number or a name — postgres, 5432, https — and the table narrows instantly.

Security-group reviews go faster when the numbers have names attached.
