# WHATPORT(8899)

## NAME

port 8899 — ospf-lite (registered) — Registered as ospf-lite; in practice a round number people grab for their own services.

Protocol: TCP/UDP  
IANA: ospf-lite

## DESCRIPTION

IANA registers 8899 on TCP and UDP as ospf-lite. Real OSPF is not a TCP service at all — it runs directly over IP protocol 89 — so this registration is for a specific product's lightweight variant rather than the routing protocol you know. Nothing widespread listens here, which leaves 8899 as another memorable HTTP-alt number that applications and proxies choose for themselves.

## EXPOSURE

**Expose with care.** Identify the owning process first; the registry name tells you nothing useful about what is answering.

## CHECK

```sh
sudo lsof -nP -iTCP:8899 -sTCP:LISTEN
```
