DNS servers primarily use the "Domain Name System" or "DNS" protocol to communicate with each other. The DNS protocol operates on UDP (User Datagram Protocol) or TCP (Transmission Control Protocol) at the transport layer of the internet protocol suite.
When DNS servers need to communicate with each other to resolve domain names or exchange DNS information, they typically use the DNS protocol over UDP for most DNS queries. UDP is a lightweight, connectionless protocol that offers fast communication but does not guarantee reliability or error correction.
However, in certain cases where the DNS response exceeds the maximum size limit of UDP packets (around 512 bytes), DNS servers may switch to TCP for DNS communication. TCP provides reliable and ordered transmission of data, making it suitable for larger DNS responses and other situations where reliability is crucial.
DNS servers communicate with each other using a combination of DNS query messages and DNS response messages. These messages contain various DNS record types, such as A records, CNAME records, NS records, and more, which allow DNS servers to resolve domain names and provide the necessary information for the resolution process.
Overall, the DNS protocol enables DNS servers to exchange information and work together to provide domain name resolution services, translating domain names into their corresponding IP addresses and facilitating communication across the internet.

DNS servers use the DNS protocol (Domain Name System protocol) to communicate with each other. The DNS protocol is a standard protocol used for resolving domain names into IP addresses and vice versa.
When a DNS server receives a query for a domain name, it can either resolve the query locally if it has the necessary information in its cache, or it can communicate with other DNS servers to obtain the required information.
To communicate with other DNS servers, the DNS protocol uses a combination of UDP (User Datagram Protocol) and TCP (Transmission Control Protocol). The majority of DNS queries and responses use UDP, which is a lightweight and connectionless protocol suitable for quick exchanges of small amounts of data. However, in some cases where the data size exceeds the limits of UDP, DNS can fall back to TCP for reliable and larger data transfers.
DNS servers communicate with each other by sending queries and responses using the DNS protocol, allowing them to exchange information and provide the requested domain name resolution across the DNS infrastructure.

DNS servers primarily use the DNS (Domain Name System) protocol to communicate with each other. The DNS protocol operates at the Application Layer of the TCP/IP protocol stack. It uses a client-server architecture where DNS clients (usually DNS resolvers) send queries to DNS servers (often called DNS name servers) to resolve domain names into IP addresses or retrieve other DNS information.
The DNS protocol uses both UDP (User Datagram Protocol) and TCP (Transmission Control Protocol) as transport protocols, depending on the circumstances. UDP is typically used for DNS queries and responses that fit within a single packet and require faster communication. TCP is used when the DNS response or query exceeds the maximum size of a UDP packet or when the communication needs to be reliable and error-free.
DNS servers communicate through a combination of recursive and iterative queries. When a DNS resolver (client) sends a query to a DNS server, it can be either recursive or iterative. In a recursive query, the DNS server fully resolves the query and returns the final answer to the client. In an iterative query, the DNS server provides the best possible answer it has or refers the client to another DNS server for further resolution.
DNS servers communicate with each other by exchanging DNS messages, which are structured packets containing various fields, including the query type, domain name, and response data. These messages are sent between DNS servers to facilitate the resolution of domain names into IP addresses and the distribution of DNS information across the internet.
Overall, the DNS protocol enables DNS servers to communicate and collaborate in resolving domain names, caching DNS records, and ensuring the proper functioning of the Domain Name System.
