HTTPDNS

System DNS may be good enough most of the time, but mobile and large-scale businesses still keep pulling name resolution back into the application. They are not reinventing a slower wheel. They are taking the resolution control point back.

Once a business starts caring about carrier-path interference, local access steering, canary routing, cross-network consistency, and resolution observability, the system resolver’s “it can return an address” answer is no longer always enough. HTTPDNS appears because many applications do not really want one standard DNS query. They want an address decision they can control themselves.
