Could a website be running from a NAS, router or other small device?¶

Yes. Many network-attached storage devices, routers, cameras and small computers can run web services. Some provide them as standard; others allow applications or packages to be installed.

Do not look only for a conventional server¶

A NAS may host files, a database and a website. A router may expose an administration page or added service. A small single-board computer may perform the same role as a larger server while being easily overlooked.

Think in terms of function rather than appearance: a device is acting as a server if it listens for requests and supplies a service.

Potential evidence includes installed packages, website files, user accounts, configuration, access logs, remote-access credentials and network settings. Router, DHCP or device-management records may connect its changing private IP address to a hardware identifier.

Small devices can have limited storage and may overwrite logs quickly. Power loss, reset buttons or removal of storage can change state or trigger recovery behaviour. An unfamiliar active device should not be casually powered down or reconnected without an appropriate plan.

Physical ownership still does not establish use. The device may be shared, remotely administered or compromised.
