### TLS mit SNI-Erweiterung

**Nur ein Prozess** im Server kann an einem bestimmten **Port** einer bestimmten **IP-Adresse** lauschen. Möglicherweise gibt es andere Prozesse, die an anderen Ports dieselbe IP-Adresse abhören, jedoch nur einen für jede Kombination aus IP-Adresse und Port.

TLS (HTTPS) verwendet standardmäßig den spezifischen Port `443`. Das ist also der Port, den wir brauchen.

  private var nextAddress = 0xff000064L // 255.0.0.100 in IPv4; ::ff00:64 in IPv6.

  }

  /** Clears the results for `hostname`.  */
  fun clear(hostname: String): FakeDns {
    hostAddresses.remove(hostname)
    return this
  }
