# WHATPORT(1047)

## NAME

port 1047 — neod1 (Sun NEO Object Request Broker) — The first of two ports registered to Sun's NEO Object Request Broker, a CORBA product long since discontinued.

Protocol: TCP/UDP  
IANA registry

## DESCRIPTION

IANA assigns 1047 to `neod1`, "Sun's NEO Object Request Broker", with no registration date and no reference document; 1048 carries the matching `neod2`. NEO was Sun's mid-1990s distributed-object platform built on CORBA, and it has not been a shipping product for decades, so there is no live software to meet here. An open 1047 today is essentially always something else — commonly a low-range dynamic RPC endpoint on an older Windows host.

## EXPOSURE

**Expose with care.** The registered ORB is extinct; whatever is listening is unidentified, and an object request broker of any kind is an unauthenticated code-invocation surface you would keep internal.

## CHECK

```sh
nmap -Pn -sV -p 1047,1048 TARGET
```
