This article introduces the relevant knowledge of "what is the meaning of dns domain name resolution". In the operation of actual cases, many people will encounter such a dilemma. Then let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!

1. What is DNS domain name resolution:

What is dns domain name resolution? what is the process of dns domain name resolution? The following editor will bring you an answer.

1. What is DNS domain name resolution:

We are used to recalling domain names, but machines only recognize IP addresses each other. There is a many-to-one relationship between domain name registration and IP addresses. An ip address does not necessarily correspond to only one domain name, and a domain name can only correspond to one ip address. The conversion between them is called domain name resolution. Domain name resolution needs to be done by a dedicated domain name resolution server, and all processes are carried out actively.

2. The process of DNS domain name resolution:

The simplest echo is an address record (also known as A record). When the client creates a query, the authorized DNS server under the domain echoes one or more IP addresses.

There is no fixed order here, and this address is usually sorted at random. Another customer may get a completely different order of results. Our customers will choose an IP in the meantime. If only a separate IP is returned, the selection process will be very short.

3. DNS domain name resolution process:

The first step: the client puts forward a domain name resolution request and sends the request to the local domain name server.

Step 2: when the local domain name server receives the request, it will first query the local cache. If there is a record entry, the local domain name server will directly return the query results.

Step 3: if the record is not in the local cache, the local domain name server sends the request directly to the root domain name server. then the root domain name server comes back to the local domain name server to give the local domain name server the address of the primary domain name server of the queried domain (the subdomain of the root).

Step 4: the local server sends a request to the domain name server that came back in the previous step, and then the server that accepts the request queries its own cache, and if there is no such record, it comes back to the address of the subordinate domain name server concerned.

Step 5: repeat step 4 until you find an accurate record.

Step 6: the local domain name server saves the returned results to the cache for next use, and returns the results to the client together.

The above is about the dns domain name resolution and the specific process of the answer, I hope to help you.
