The whole process can be completed in just a few seconds.

2, Mac system end point query

open the startup of the Mac system, find the end point program in another folder and start it. Enter the nslookup command in the end point to view the default DNS resolution address, and enter the nslookup target domain name to query the resolution record of the specified domain name. In addition, you can also enter the dig target domain name command to get more detailed DNS resolution address related information, including resolution type, TTL value and other professional parameters.

How to check the DNS resolution address through the online platform?

if you don't want operating system commands, or need to query DNS resolution addresses across network environments, various online query platforms are good choices. Such platforms can be used directly through the browser without downloading software.

1, professional DNS query website

there are many professional DNS query websites in China, such as webmaster tools, love station network, etc. After entering the website, find the DNS query section, enter the domain name to be queried, and select the corresponding resolution type, you can quickly obtain the DNS resolution address of the domain name and related resolution records. Such platforms will also provide a comparison of the resolution results of multi-regional nodes to help users judge whether there are regional differences in DNS resolution addresses.

2, public DNS service provider query page

public DNS service providers such as Alibaba Cloud and Tencent Cloud provide DNS resolution address query function on the official website. After entering the corresponding page, users can enter the domain name to query the resolution result of the domain name on their DNS server. At the same time, they can also understand the coverage and resolution speed of the service provider's DNS resolution address, so that users can choose a more suitable public DNS resolution address for themselves.

1, domain name resolution list query

log in to the management background of the domain name service provider, find the domain name management or DNS resolution management section, and enter to see all the configured DNS resolution address records of the domain name, including A records, CNAME records, MX records and other different types of resolution information. Each record will display the corresponding target address, TTL value and other parameters. Users can directly view or modify these DNS resolution address configurations.

2, DNS server address verification

in the background of the domain name service provider, you can also view the DNS server address used by the current domain name, that is, the authoritative DNS resolution address responsible for resolving the domain name. Users can determine whether there is an access abnormality caused by the resolution cache by comparing the address with the DNS resolution address used locally. At the same time, they can accurately configure the new DNS resolution address information when changing the DNS server.

4. Precautions for querying DNS resolution addresses?

in the process of querying DNS resolution addresses, there are some details that need to be paid attention to, which can help users obtain more accurate query results and avoid misjudgments.

1, distinguish between local cache and real parsing results

system tool may come from the local cache, not the real-time authoritative resolution result. If you need to get the latest DNS resolution address, you can clear the local DNS cache first, Windows system can enter ipconfig /flushdns in the command prompt, Mac system can enter sudo dscacheutil -flushcache in the end point, clear the cache and then query to get more accurate results.

2, pay attention to the type difference of parsing records

DNS resolution address contains a variety of record types. Different types of resolution records correspond to different network service requirements. For example, A records are used to point domain names to IPv4 addresses, AAAA records to IPv6 addresses, and MX records are used for mail service queries. When querying, choose the corresponding record type according to your own needs to avoid querying irrelevant DNS resolution address information.

sum up, there are many ways to query DNS resolution addresses, and users can choose the appropriate way according to their own needs and operating habits: system tools are suitable for quickly querying the DNS resolution address of local or designated domain names, online platforms can provide multi-dimensional analysis results comparison, and domain name service providers The background is the best channel to view and manage the DNS resolution address of their own domain names. After mastering these methods, whether it is troubleshooting network problems or optimizing domain name resolution configuration, it can be easily completed, making network access more stable and efficient.
