# WHATPORT(1057)

## NAME

port 1057 — STARTRON — Registered as STARTRON; no public protocol documentation, and among the rarest ports in this block.

Protocol: TCP/UDP  
IANA registry

## DESCRIPTION

IANA assigns 1057 to `startron`, "STARTRON", a vendor registration with no published specification or surviving product documentation. Nmap's frequency data puts it near the bottom of this range, around 0.04% of scanned hosts. There is genuinely nothing further to report about the registered service. Anything listening on 1057 in a modern network should be identified from its banner and the owning process, not from this name.

## EXPOSURE

**Expose with care.** Unknown service; the exposure decision belongs to whatever is actually bound there, so fingerprint it first.

## CHECK

```sh
nmap -Pn -sV -p 1057 TARGET
```
