# WHATPORT(7770)

## NAME

port 7770 — Unassigned — Also unassigned, seven ports below 7777 — no registered service, no default product.

Protocol: TCP  
IANA registry

## DESCRIPTION

7770 falls inside IANA's unassigned 7748-7776 range and has no service name in Nmap's database, which puts it at roughly 0.015% open-port frequency. Its only notable feature is proximity: hosts running game or application servers around 7777 sometimes have neighbours in this range because an operator assigned a block by hand.

## EXPOSURE

**Expose with care.** Nothing about the number implies safety; identify the listener, and if it belongs to a game or application server cluster, rate that service instead.

## CHECK

```sh
nmap -Pn -sV -p 7770 TARGET
```
