This article is about how to dns domain name resolution, the editor thinks it is very practical, so I share it with you to learn. I hope you can get something after reading this article. Let's take a look at it.

The dns domain name resolution process, for example, a domain name is: abc.com, is to see the current HTTP service, if you want to visit the website, you need to resolve it. First, resolve to a fixed IP of a WEB server through a special DNS server at the domain name registrar: 1xx.2xx.1.1xx, and then receive the domain name through the web server, and map the abc.com domain name to this server. Then, enter the domain name abc.com to access the content of the website, that is, to achieve the whole process of domain name resolution.

Common types of domain names resolved by DNS:

1. Analysis of A record

Select "A" for the record type; enter the IP address of the host provided by the space provider for the record value; the MX priority does not need to be set; the default TTL setting is 3600.

2. Analysis of CNAME records

The CNAME type resolution setting method is basically the same as the A record type, where the record type is changed to "CNAME" and the record value is filled in the server host address.

3. Analysis of MX records

MX record parsing is used for mailbox parsing. Select MX as the record type, select general line type or add records with three line types as Telecom, Netcom and Education Network at the same time; the record value should be filled in the IP address or alias address of the server provided by the post office provider; the default TTL can be set to 3600, and the MX priority should be filled in the data required by the post office provider, or 10 by default. When there are multiple MX records, the priority should be set to different data.

The fee incurred for resolving a domain name is generally purchased from the same cloud service provider, then DNS provides it free of charge. If you are not in the same company, you need to purchase an additional DNS address.
