# WHATPORT(1037)

## NAME

port 1037 — ams — Registered in 2004 as "AMS" — an acronym with no expansion, no spec, and no implementation on record.

Protocol: TCP/UDP  
IANA registry

## DESCRIPTION

IANA assigns 1037 to `ams`, described only as "AMS", registered in February 2004 to an individual assignee with no reference document. The registry does not expand the acronym and there is no published protocol behind it, so the honest description is that the port is claimed and unused. Open ports at 1037 in the field are almost always unrelated: dynamic RPC endpoints on old Windows systems, or an application that bound the first free port above 1024.

## EXPOSURE

**Expose with care.** Nothing documented to reason about — resolve the owning process locally before treating an open 1037 as benign.

## CHECK

```sh
sudo lsof -nP -iTCP:1037 -sTCP:LISTEN
```
