Intel device on my network
Intel is the American chip company; its registry entry Intel Corporate covers the Wi-Fi and Ethernet chips in a very large number of PCs.
What Intel makes
Intel Wi-Fi cards (such as the AX200, AX201, AX210 and BE200 families) and Intel Ethernet controllers are built into a large share of Windows laptops and desktops, and many Linux machines and mini PCs. The PC brand on the lid might be Dell, HP, Lenovo, or anyone else.
What the device on your network probably is
Almost certainly a laptop or desktop PC, most often a Windows laptop. Less often a mini PC, a home server or a NAS with Intel networking.
How to work out which device it is
On each Windows PC run ipconfig /all and compare the Physical Address; on Linux use ip link. The router's hostname column usually shows the computer name. If Windows is set to use random hardware addresses, the entry will show as a private address instead.
Should you be worried
Nothing to worry about: it is a computer's network card. If you do not recognise the computer name, check with others in the household before anything else.
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.
