# WHATPORT(1864)

## NAME

port 1864 — paradym-31port — "Paradym 31 Port" — a name in the registry and nothing else.

Protocol: TCP  
IANA registry

## DESCRIPTION

IANA assigns 1864 (TCP and UDP) to "paradym-31port", registered by David Wooden with the description "Paradym 31 Port". No specification, vendor documentation, or current implementation is publicly available. Its practical significance is that it sits directly above 1863, so it occasionally gets swept up in scans looking for MSN-era software rather than for anything to do with Paradym.

## EXPOSURE

**Expose with care.** Nothing widely deployed claims this port, so an open 1864 is an unidentified service and should be traced to its process before it is allowed through anything.

## CHECK

```sh
nc -vz -w 3 TARGET 1864
```
