Using Microsoft Defender VPN Still Allows Me to Set DNS Server at the Router?
We have a base router and one satellite in our home. One year ago I went into Orbi's settings and changed the DNS servers to be 1.1.1.3 and 1.0.0.3 from Cloudflare because our young kids had just st...

Well, considering the design goals for Microsoft Defender for Endpoint and your privacy on Android and iOS mobile devices it's unlikely the DNS queries from these device endpoints will never reach the Orbi DNS server configured ever.

Thanks for finding that link. So, Microsoft Defender for Endpoint is not a VPN in the traditional sense:
Conveniently left out of the article is how URLs are resolved into IP addresses. After Defender has determined that the proposed connection is not a threat, apparently the connection proceeds normally. Perhaps a DNS request is made as usual, in which case it would go to whatever DNS server is defined in the device wireless configuration. Orbi DHCP specifies the Orbi router as the DNS server. On computers, it is not difficult to configure actual DNS servers in the wireless settings instead of using the server specified by DHCP. (Not clear to me whether iPhones have the same capability.)
I'd love to see happens on this iPhone using Microsoft Defender for Endpoint. Not certain how to explain if a specific URL is blocked. (a) did Defender block it? or, (b) did CloudFlare block it?
