# WHATPORT(8987)

## NAME

port 8987 — Unassigned — Unassigned by IANA, with no service that commonly claims it.

Protocol: TCP  
IANA registry

## DESCRIPTION

IANA lists 8982–8988 as Unassigned, so 8987 has no registration and no protocol you can assume from the number alone. It is close enough to 8983 — Apache Solr's default — that it turns up on the same hosts as an extra or second-instance port, but that is a local choice, not a convention. Look at the process, not the number.

## EXPOSURE

**Expose with care.** Unregistered does not mean harmless; whatever bound it may be a search index or admin endpoint that expected to be private.

## CHECK

```sh
sudo lsof -nP -iTCP:8987 -sTCP:LISTEN
```
