# WHATPORT(7278)

## NAME

port 7278 — OMA Dynamic Content Delivery over CBS — An Open Mobile Alliance registration for Dynamic Content Delivery over Cell Broadcast Service.

Protocol: TCP/UDP  
IANA registry

## DESCRIPTION

IANA registered 7278 in January 2008 as oma-dcdocbs, "OMA Dynamic Content Delivery over CBS". DCD was an Open Mobile Alliance enabler for pushing channel-based content to handsets, and this assignment covers the variant carried over the cellular Cell Broadcast Service. It belongs to operator-side mobile infrastructure of that era, not to general-purpose servers, and it is close to unseen in internet-wide scanning. If it is open on a host you administer, the listener is almost certainly something unrelated that picked the number.

## EXPOSURE

**Expose with care.** Nothing generic runs here, so an open 7278 is an unidentified service; find the process before deciding anything about it.

## CHECK

```sh
nc -vz TARGET 7278
```
