# WHATPORT(1112)

## NAME

port 1112 — ICP / mSQL (legacy) — IANA says Intelligent Communication Protocol; Nmap's TCP entry says msql, from early Mini SQL releases.

Protocol: TCP  
IANA registry

## DESCRIPTION

IANA registers 1112 as icp, the Intelligent Communication Protocol. Nmap's service list names the TCP side msql and carries "mini-sql server" among its alternate names, reflecting early Mini SQL builds that listened here before the database settled on its registered port 1114. Neither service is common today; Nmap's frequency data places 1112 near the bottom of what scans find open.

## EXPOSURE

**Do not expose.** If the listener is an mSQL database, it is a database port and belongs on localhost or a private network; if it is something else, you need to identify it before exposing it at all.

## CHECK

```sh
nmap -Pn -p 1112 -sV TARGET
```
