15// An implementation of cricket::PortAllocator for libjingle that is
16// used by the client plugin. There are two differences from
17// cricket::HttpPortAllocator:
18//   * PepperPortAllocator uses Pepper URLLoader API when creating
19//     relay sessions.
20//   * PepperPortAllocator resolves STUN DNS names and passes IP
21//     addresses to BasicPortAllocator (it uses HostResolverPrivate API
22//     for that). This is needed because libjingle's DNS resolution
23//     code doesn't work in sandbox.
