ADAPTER_TYPE_ANY can be used to set the network ignore mask if an application does not want candidates from the any address ports, the underlying network interface types of which are not determined in gathering. The ADAPTER_TYPE_ANY is also given the maximum network cost so that when there are candidates from explicit network interfaces, these candidates from the any address ports as backups, if they ever surface, are not preferred if the other candidates have at least the same network condition.
