DNS servers typically use the UDP (User Datagram Protocol) protocol to communicate with each other to resolve DNS queries. UDP is a lightweight, connectionless protocol that allows DNS servers to send queries and receive responses without establishing a persistent connection. DNS queries and responses are encapsulated in UDP packets, which are sent over port 53, the standard port for DNS communication.
UDP is favored for DNS because it is faster and more efficient than TCP (Transmission Control Protocol), which is a connection-oriented protocol. UDP does not require the overhead of establishing and maintaining a connection, making it suitable for the quick exchange of small-sized DNS packets. However, if a DNS response exceeds the maximum UDP packet size (typically 512 bytes), TCP can be used instead.
It's worth noting that while UDP is the primary protocol used for DNS queries and responses between DNS servers, client devices (such as web browsers or applications) may use both UDP and TCP to communicate with DNS servers, depending on the specific circumstances and requirements of the DNS query.

DNS (Domain Name System) servers typically use the UDP (User Datagram Protocol) protocol to communicate with each other. UDP is a lightweight and connectionless transport protocol that allows DNS queries and responses to be exchanged efficiently.
The DNS protocol operates on top of the transport layer protocols, and it can use both UDP and TCP (Transmission Control Protocol). UDP is the preferred choice for DNS queries due to its lower overhead and faster transmission compared to TCP.
DNS queries sent over UDP use port 53 as the default destination port. The DNS server listens on this port to receive incoming queries. UDP is suitable for most DNS queries as they are typically small in size and can fit within the maximum size of a UDP packet.
However, in certain cases where the DNS response is larger than the maximum UDP packet size, DNS servers may switch to TCP for communication. TCP provides reliable, connection-oriented communication, and it uses port 53 as well.
In summary, DNS servers primarily use the UDP protocol for communication, while TCP may be utilized in situations where larger DNS responses or other exceptional circumstances require it.

DNS servers typically use the DNS protocol to communicate with each other to resolve DNS queries. The DNS protocol operates over UDP (User Datagram Protocol) or TCP (Transmission Control Protocol) on port 53. When a DNS resolver needs to resolve a domain name, it sends a DNS query to a DNS server, which then responds with the corresponding IP address or provides further information needed to resolve the query. This communication between DNS servers using the DNS protocol allows for the hierarchical and distributed nature of the DNS system.

DNS servers typically use the DNS protocol, specifically the UDP (User Datagram Protocol) or TCP (Transmission Control Protocol) transport protocols, to communicate with each other and resolve DNS queries.
UDP is the most commonly used transport protocol for DNS queries. It is lightweight and faster than TCP due to its connectionless nature, which means it does not establish a persistent connection between the client and the server. DNS queries and responses using UDP are sent as individual packets, allowing for quicker exchanges.
However, in some cases, TCP may be used for DNS communication. TCP provides a reliable, connection-oriented communication, which is useful for large DNS responses that exceed the maximum size of a UDP packet. DNS over TCP is typically used when UDP is not available or when dealing with certain types of DNS queries, such as zone transfers.
DNS servers can communicate with each other using either UDP or TCP depending on the specific circumstances and configuration. UDP is the primary choice for regular DNS queries due to its efficiency, while TCP is used when specific conditions require a more reliable and connection-oriented approach.
