Unassigned at IANA — nothing standard lives here.
IANA lists port 32 as Unassigned on both TCP and UDP, with no assignee and no reference document. No common service binds it as a default. As with the other unassigned low ports, an open 32 is a custom listener and the number itself carries no information. Identify the process holding the socket before drawing any conclusion.
Expose with care
Unregistered, so exposure depends entirely on the unidentified service behind it.
