What Realtek makes

Realtek network chips are in USB Wi-Fi and Ethernet adapters, PC motherboards, laptops, smart TVs, set-top boxes, routers and cheap IoT devices. Most products using a Realtek chip carry their own brand's address, so a Realtek-registered address often means the manufacturer used the chip's default address rather than buying its own.

What the device on your network probably is

Most likely a USB Ethernet or Wi-Fi adapter, a PC or laptop with a Realtek network chip, or a smart TV or streaming box. Less often an inexpensive smart-home gadget or camera.

How to work out which device it is

Check any USB network adapters and docks first; unplugging them is the quickest test. On a PC, ipconfig /all shows each adapter's address. Otherwise power devices down one at a time.

Should you be worried

Usually nothing to worry about. Realtek made the chip, and many different products use it, so the name alone cannot tell you what it is.

ON YOUR PHONE · LAN SCAN

The app finds every device on the Wi-Fi you are on, at home or in a rental, and puts the vendor next to the hostname, the services it advertises and its open ports, which together usually name the product. Where it cannot tell, it says so instead of guessing. Get RECON for iPhone — one-time purchase, no account, nothing leaves the device.
