What Port 1970 Does
Port 1970 (TCP and UDP) carries traffic for NetOp Remote Control, an enterprise remote desktop and administration platform. NetOp lets administrators access, control, and support remote computers across LANs, WANs, and the Internet — screen sharing, file transfer, and full keyboard/mouse control over a distant machine.
The IANA registry lists port 1970 under "Netop Business Solutions Netop Remote Control."1 Related ports 1971, 6502, and 6503 serve companion NetOp products.
The Story Behind the Port
In 1987, in a cramped office in Herlev, Denmark, a programmer at Danware Data had a problem: the development servers lived under the kitchen sink. Every crash, every restart, every configuration change meant physically walking to the sink, crouching down, and fiddling with a machine that had no business being there.2
So he built NetOp — a DOS program that fit in under 1 KB of memory — to control the server from his desk.
That absurd, domestic origin produced software that eventually ran on the systems of half the Fortune 100. Banks, retailers, critical infrastructure. All because someone refused to keep crawling under furniture.
By 2008, Danware renamed itself Netop Solutions. In 2021, Impero Software acquired the company and rebranded the product as Impero Connect, but the underlying technology — and port 1970 — carried forward.3
The Registered Port Range
Port 1970 sits in the registered ports range (1024–49151). These ports aren't reserved for the big household-name protocols. They're the middle tier: formally registered with IANA by companies and projects with a real service to identify, but requiring no special OS privilege to open.
This is where the workhorses live — proprietary enterprise tools, database servers, game backends. The range is large enough that many ports in it go unassigned. Port 1970 is one that didn't.
Is This Port a Security Concern?
Remote control software is inherently dual-use. NetOp is a legitimate enterprise product with authentication and encryption — but any tool that hands over keyboard and mouse control to a remote party deserves careful firewall rules. If you're not running NetOp, port 1970 shouldn't be open.
Attackers occasionally probe registered ports looking for misconfigured or unpatched remote-access tools. Standard hygiene applies: block it at the perimeter unless you specifically need it.
