The Domain Name System (DNS) is a protocol that uses both TCP and UDP. Here's how:

1. UDP: User Datagram Protocol is typically used for DNS. When you type a website URL into your browser, a DNS query is sent to your internet service provider (ISP) to look up the IP address of the domain. This is usually a small request, so it's sent using UDP, which is faster because it doesn't require a formal connection setup like TCP.

2. TCP: Transmission Control Protocol is used by DNS for tasks that require more reliability and are larger in size. For example, when a DNS response data size exceeds 512 bytes, or for tasks like zone transfers between servers, TCP is used.

So, DNS uses both TCP and UDP depending on the situation and requirement.
