    <p>Grazie per il link Andrea, interessante, non lo conoscevo. Mi
      chiedo se è permessa ancora la vendita dei dati ISP ai "data
      brokers" in Europa da quando il GDPR è  entrato in funzione. Ne
      sei a conoscenza ?<br>
    </p>
    <p>Aggiungo alcuni link:</p>
    <ul>
      <li>alcuni recenti (nov. 2020) dati estratti da RIPE (Nic Europa)
        sull'analisi delle query DNS:

        <br>
      </li>
    </ul>
    <ul>
      <li>un rapporto di Internet Society sul consolidamento di alcune
        posizioni centralizzate di mercato e di traffico (include DNS
        privati) <a class="moz-txt-link-freetext" href="https://future.internetsociety.org/2019/">https://future.internetsociety.org/2019/</a> . Interessanti
        le risposte adottate dai governi in vari stati per contrastare
        questa centralizzazione:

        <br>
      </li>
    </ul>
    <p>A lato pratico, se vuoi incominciare ad usare il DNS indicato da
      Andrea, basta cambiare una voce in /etc/resolv.conf ed è fatta :)<br>
