 DNS has existed since the [early days](https://en.wikipedia.org/wiki/Domain_Name_System#History) of the Internet. DNS requests made to and from DNS servers are **not** generally encrypted. In a residential setting, a customer is given servers by the ISP via [DHCP](https://en.wikipedia.org/wiki/Dynamic_Host_Configuration_Protocol).
 
-Unencrypted DNS requests are able to be easily **surveilled** and **modified** in transit. In some parts of the world, ISPs are ordered to do primitive [DNS filtering](https://en.wikipedia.org/wiki/DNS_blocking). When you request the IP address of a domain that is blocked, the server may not respond or may respond with a different IP address. As the DNS protocol is not encrypted, the ISP (or any network operator) can use [DPI](https://en.wikipedia.org/wiki/Deep_packet_inspection) to monitor requests. ISPs can also block requests based on common characteristics, regardless of which DNS server is used. Unencrypted DNS always uses [port](https://en.wikipedia.org/wiki/Port_(computer_networking)) 53 and always uses UDP.
