# WHATPORT(7725)

## NAME

port 7725 — nitrogen — Registered as "Nitrogen Service" to an individual, with no public protocol behind the name.

Protocol: TCP  
IANA registry

## DESCRIPTION

IANA lists 7725 as nitrogen, Nitrogen Service, assigned to Randy Lomnes. There is no published specification, RFC, or open implementation tied to that registration, and Nmap sees the port open on roughly 0.015% of hosts. The name is not the Nitrogen Erlang web framework, which serves ordinary HTTP. In practice a listener on 7725 is a private application and the registration will not identify it for you.

## EXPOSURE

**Expose with care.** A registered name with no specification tells you nothing about authentication or encryption; identify the service before exposing it.

## CHECK

```sh
nmap -Pn -sV -p 7725 TARGET
```
