# WHATPORT(45100)

## NAME

port 45100 — Unassigned — Another round unregistered number — chosen by hand when it is chosen at all.

Protocol: TCP  
IANA registry

## DESCRIPTION

IANA lists nothing for 45100 and Nmap has no name for it, though its open frequency of about 0.07% is on the higher side for this neighbourhood. Tidy numbers like 45100 are typical picks for internal or vendor-specific services that never bothered with a registration. Being inside the Linux ephemeral range, it also collects incidental client sockets.

## EXPOSURE

**Expose with care.** Unregistered does not mean unimportant — run a version scan, and if it turns out to be an admin or database interface, treat it by what it is, not by its port.

## CHECK

```sh
nmap -sV -Pn -p 45100 TARGET
```
