# WHATPORT(8701)

## NAME

port 8701 — Unassigned — No IANA assignment on either transport, and no documented default service.

Protocol: TCP/UDP  
IANA registry

## DESCRIPTION

8701 is absent from the IANA registry for both TCP and UDP. Nmap lists it as "unknown", open on roughly 0.08% of scanned TCP hosts and 0.03% of UDP hosts — low, but a little higher than most of its unregistered neighbours, which usually means a handful of products picked it independently rather than one well-known service. Nothing mainstream documents it as a default.

## EXPOSURE

**Expose with care.** An unlabelled port with no registry meaning. Find the owning process and judge exposure on that, not on the number.

## CHECK

```sh
sudo lsof -nP -iTCP:8701 -sTCP:LISTEN
```
