# WHATPORT(24444)

## NAME

port 24444 — Unassigned — Unassigned by IANA — a memorable repeated-digit number that developers pick by hand, not a registered service.

Protocol: TCP  
IANA registry

## DESCRIPTION

24444 sits in IANA's unassigned block 24387-24464 with no registration on TCP or UDP. Nmap records it as 'unknown' on both, which puts the TCP side in the default top-1000 list. Repeated-digit ports like this get chosen ad hoc for local daemons, test harnesses, and debug listeners because they are easy to remember, so an open 24444 is usually somebody's own service rather than a product default. Nothing standard is defined here.

## EXPOSURE

**Expose with care.** Hand-picked development ports are the ones most often left bound to 0.0.0.0 by accident. Check what it is and whether it should be listening at all.

## CHECK

```sh
nmap -Pn -sV -p 24444 --reason TARGET
```
