I recently came upon a curious WiFi access point branded “Datapipe Wireless”
Although the network is “Open” it required Phone number verification for internet access (Very odd for a US WiFi Provider).
The sign-on page was hosted by n123.network-auth.com, a private domain with an IP address resolving to a CDN network.
After connecting, I was taken to a “Cisco Meraki” confirmation page, indicating the brand of hardware the WiFi point is using.
The WiGLE map of the access point “Datapipe Wireless” indicates it’s only on a single block of San Jose.
