An IANA name reservation for ITACTIONSERVER 2 and almost nothing else — a listener here is host-specific.
IANA registers 7280 as itactionserver1 and 7281 as itactionserver2, both to an individual assignee (Brian Taylor) with no public specification attached. There is no open protocol document, no reference implementation, and no widely deployed product that advertises this port. Nmap's service-frequency data puts it at roughly 0.015% of open TCP ports, which is registry noise rather than real deployment. If you find it listening, the registration tells you nothing useful — identify the process locally instead.
Expose with care
You cannot rate a port whose service you have not identified; find the owning process with lsof or ss before deciding whether it belongs on a public interface.
