Website construction domain name resolution: how to associate a domain name with a server?

Registered your domain name (your website address), purchased your server (your website house), and now you need to tell the world.“Hello! My home (website) is at this new address (server IP), please follow this new address to me!”This process of “showing the way” is calleddomain name resolution。

Don't be intimidated by the terminology, it's very simple in nature. Let's understand it step by step.

​First, the core concept: what is domain name resolution?​

Imagine the address book of the Internet world:

• ​Domain.Hi. Friend's name.“Zhang San”(Good to remember, but I don't know where he is).
• Server IP address.Zhang San'sActual door number​ ​“XX City, XX Road, No. XX.”(Exact location, but hard to remember).
• ​Domain name resolution.It's accessing the address book, based on the name“Zhang San”Find his house.“XX City, XX Road, No. XX.”The process.

On a technical level, this process is accomplished by modifying a program calledDNS recordsDNS (Domain Name System) is the global “Internet super address book”.

​To summarize: domain name resolution is the operation of pointing your easy-to-remember domain name to a server IP address.​

​Second, what do you need to prepare before parsing?​

Before you begin, make sure you have the following two key pieces of information on hand:

1. Your domain name.for example likacloud.com。
2. Your server's IP address.This is usually provided to you by the hosting provider via email or on the backend after you purchase web hosting. It looks like a string of numbers, for example 192.0.2.1。
   • Attention.What you need is the server'sIP address, rather than the host's backend login address.

     • If you want to makeexample.com(without www) to visit your site, just fill in the@。
     • (Typically, we parse both wwwand @(Two records to the same IP)
   • Recorded values.Fill in yourserver IP address(the string of numbers provided by the hosting provider).
   • TTL.Just keep the default (usually 10 minutes). It indicates how long it takes for the global DNS servers to refresh this record.

​Step 3: Save and wait for it to take effect​
