如何解析DNS服务器

DNS, or the Domain Name System, is a system that translates human-readable domain names into IP addresses. A DNS server is a server that stores the DNS records for a domain; these records include the nameservers for the domain, as well as other records such as MX records and TXT records.

When you type a domain name into your web browser, the browser contacts a DNS server to look up the IP address for that domain. The DNS server then responds with the IP address, and the browser connects to the website at that IP address.

There are many different types of DNS servers, but the most common type is the recursive DNS server. A recursive DNS server is a server that can resolve DNS queries for itself, as well as for other clients.

Most DNS servers are configured to be recursive DNS servers, which means that they can resolve DNS queries for any domain. However, some DNS servers are configured as forwarders, which means that they can only resolve DNS queries for a limited set of domains.

When a DNS server receives a DNS query, it first checks to see if it can resolve the query itself. If the DNS server can resolve the query, it will return the answer to the client. If the DNS server cannot resolve the query, it will forward the query to another DNS server.

The process of forwarding a DNS query from one DNS server to another is known as DNS recursion. DNS recursion can be used to resolve DNS queries for any domain, but it can also be used to resolve DNS queries for a limited set of domains.

DNS servers can be configured to use DNS recursion to resolve DNS queries for a limited set of domains, or they can be configured to use DNS recursion to resolve DNS queries for any domain.
