# WHATPORT(27355)

## NAME

port 27355 — Unassigned — Unassigned on TCP and UDP, part of the 27352-27356 cluster of unnamed scan hits.

Protocol: TCP  
IANA registry

## DESCRIPTION

27355 is inside IANA's unassigned range 27346-27441 and has no registration. Nmap carries 'unknown' entries for it on both TCP and UDP. Its open-frequency matches its neighbours 27352, 27353 and 27356 closely enough that the four are effectively one scanning artefact rather than four distinct services. Nothing verifiable identifies what answers.

## EXPOSURE

**Expose with care.** Treat as an unknown listener. A version scan is the only thing that turns this into a real verdict.

## CHECK

```sh
nmap -Pn -sV -p 27355 --reason TARGET
```
