Domain name resolution address refers to the process of converting domain names into IP addresses. In the Internet, each device has a unique IP address, and domain names exist to facilitate people's memory. Domain name input can be converted into the corresponding IP address through domain name resolution, thereby realizing network communication. So, how to check the domain name resolution address?

First, we need to understand the principles of domain name resolution. In the Internet, domain name resolution is completed through DNS servers. DNS server is a special server that stores a large amount of domain name and corresponding IP address information. When we enter a domain name, the computer will send a request to the DNS server, requesting the DNS server to return the corresponding IP address. The DNS server will return the corresponding IP address based on its own records, and the computer will communicate with the target device based on this IP address.

So, how to check the domain name resolution address? Here are several methods.

Method 1: Use the ping command

The ping command is a commonly used network tool, which can be used to test network connections and view domain name resolution addresses. In a Windows system, open a command prompt window and enter ping plus the domain name to be queried, for example:

ping www.google.com

After pressing the Enter key, the system will send a request to the DNS server and return the corresponding IP address. If the connection to the target device is successful, a message similar to the following will be displayed:

Pinging www.eg.com [127.0.0.1] with 32 bytes of data:

Reply from 127.0.0.1: bytes=32 time=22ms TTL=52

Reply from 127.0.0.1: bytes=32 time=23ms TTL=52

Reply from 127.0.0.1: bytes=32 time=23ms TTL=52

Reply from 127.0.0.1: bytes=32 time=22ms TTL=52

Ping statistics for 127.0.0.1:

     Packets: Sent = 4, Received = 4, Lost = 0 (0% loss),

Approximate round trip times in milli-seconds:

     Minimum = 22ms, Maximum = 23ms, Average = 22ms

Among them, [127.0.0.1] is the IP address queried.

Method 2: Use the nslookup command

The nslookup command is also a tool for querying domain name resolution addresses. In Windows systems, also open a command prompt window and enter nslookup plus the domain name to be queried, for example:

nslookup www.google.com

After pressing the Enter key, the system will send a request to the DNS server and return the corresponding IP address. If the connection to the target device is successful, a message similar to the following will be displayed:

Server: Unknown

Address: x.x.x.x

Non-authoritative answer:

Name: www.eg.com

Addresses: 127.0.0.1

                   127.0.0.1

Among them, listed under Addresses is the IP address queried.

Method 3: Use online query tools

In addition to using command line tools, we can also use online query tools to query domain name resolution addresses. For example, if we enter "domain name resolution address query" in the google search box, a large number of online query tools will appear for us to choose from. Choose a trustworthy website, enter the domain name you want to query, and click the query button to get the corresponding IP address.

Conclusion

The above are several ways to check the domain name resolution address. Whether it is the ping command, nslookup command or online query tool, it can help us quickly query the desired IP address. Of course, in practical applications, we can also implement customized domain name resolution by modifying the hosts file.
