//
// Local network access requests are requests from a less-private IP address
// space to a more-private IP address space. Concretely:
//
//  - unknown to private
//  - unknown to local
//  - public to private
//  - public to local
//  - private to local
//
// See the Local Network Access (LNA) Spec at
// https://wicg.github.io/local-network-access/
// for more information.

  // Allow the requests, and display a warning in DevTools.

  // Block the requests with a CORS error.
  kBlock,

  // Display a warning in devtools when a request will require user permission
  // in the future when LNA launches.
  kPermissionWarn,

  // Block requests unless the user explicitly grants permission for the
  // request to proceed.
  kPermissionBlock,
