Port 3414: BroadCloud WIP Port — A Registered Ghost

What Range This Port Lives In

Port 3414 sits in the registered ports range, spanning 1024 to 49151. These ports are managed by IANA — the Internet Assigned Numbers Authority, the organization that maintains the official list of who owns what in the port numbering system.¹

The registered range is the middle tier of port space:

• Well-known ports (0–1023): Reserved for foundational Internet services. HTTP on 80, HTTPS on 443, SSH on 22. These require special OS privileges to bind.
• Registered ports (1024–49151): Where companies and developers can formally claim a port for their software by registering it with IANA.
• Dynamic/ephemeral ports (49152–65535): Assigned temporarily by the OS for outgoing connections. No registration required or expected.

Port 3414 belongs to the middle tier — registered, claimed, and officially accounted for. Whether it's actually in active use is a different question.

The Registration: BroadCloud WIP Port

IANA lists port 3414 as wip-port, assigned to BroadCloud.² Both TCP and UDP are registered.

BroadCloud was a cloud-based business communications platform — hosted PBX, unified communications, that category. Cisco acquired it as part of their broader push into cloud communications, which they now market under BroadWorks.³

What "WIP" stands for in this context is not publicly documented. Wireless IP is a reasonable guess — BroadCloud provided hosted voice services, and handling wireless IP phone traffic is exactly the kind of thing that would need a dedicated port. But this is inference, not fact.

The actual protocol specification, if one exists, has never surfaced in public documentation.

What This Means in Practice

If you see traffic on port 3414, it's most likely one of three things:

1. BroadCloud/Cisco infrastructure — Legacy BroadCloud deployments or Cisco BroadWorks-based carrier services using it for whatever WIP actually means internally.
2. Something unrelated — Port 3414 is registered but obscure. It's available real estate in a quiet neighborhood. Applications sometimes choose ports like this precisely because they're unlikely to conflict with anything.
3. A port scan or probe — Automated scanners sweep port ranges constantly. Traffic appearing on a random registered port is often just noise.

How to Check What's Listening

If port 3414 is open on your system and you want to know why:

Linux/macOS:

# Show what process is listening on port 3414
ss -tlnp sport = :3414

# Or with lsof
lsof -i :3414

# Or with netstat
netstat -tlnp | grep 3414

Windows:

netstat -ano | findstr :3414

The last column in the Windows output is the process ID (PID). Cross-reference it with Task Manager or:

tasklist | findstr <PID>

Why Obscure Registered Ports Still Matter

The port registry's value comes from its completeness. Every registered port — even the ones with thin documentation — represents a coordination point. Without registration, two pieces of software that happen to choose the same number step on each other.

The system works because most software respects it, and because IANA maintains the list without gaps. Port 3414's ghost of a registration still does its job: it tells other developers "something claimed this, pick somewhere else."

Whether BroadCloud's WIP service is alive, deprecated, or quietly powering Cisco infrastructure nobody talks about — the port number is spoken for.
