# WHATPORT(1031)

## NAME

port 1031 — Reserved — Reserved at IANA with no owner since the 2013 cleanup; any listener here is non-standard.

Protocol: TCP/UDP  
IANA registry

## DESCRIPTION

IANA lists 1031 as "Reserved", with no service name, no assignee, and the same 2013-05-24 removal note as 1030 and 1032. There is no protocol to describe. On scans it turns up as another dynamically allocated endpoint on legacy Windows systems, which used 1025-5000 for RPC and DCOM before Vista moved that range to 49152-65535.

## EXPOSURE

**Expose with care.** Nothing is registered here; identify the process behind it rather than inferring anything from the port number.

## CHECK

```sh
nc -vz TARGET 1031
```
