This article introduces you how to collect local DNS export IP, the content is very detailed, interested friends can refer to, hope to be helpful to you.

I don't know if the webmasters who like to toss around have ever shielded the IP of their computers when messing around with operations such as IP, resulting in the embarrassment of not being able to log in to the server. to tell you the truth, Mingyue has encountered it many times. Fortunately, you can log in again after rebooting the router (an IP will be reassigned to the router after a broadband connection). In fact, this problem sometimes affects the efficiency when you are messing around under Linux.

So what's a better, more scientific solution?

The answer, of course, is to collect the IP of the local DNS export, or, to put it more colloquially, the IP that your current broadband operator DNS will assign to the client. Because it is allocated to each broadband client, this data is public and can be easily obtained by using the whois command.

What? There is no whios command on your Windows command line (cmd)? There is no such command in the Linux terminal console?

Um, well, in fact, Mingyue's Windows and Linux do not have whois instructions, so what should I do? In fact, this is a "black under the light" problem, the local do not have this command, and do not want to install completely online whios command can be used! For example: webmaster tools and other online tools provide online whios commands, of course, we must distinguish between domain name whios query or IP whios query, one is to look up the domain name, and the other is to check IP.

All right, the tools are all ready, let's start our collection work!

In fact, this is a very simple thing. First of all, we need to obtain the DNS IP address of the currently used broadband, which also requires the help of a third-party tool. Here Mingyue recommends using CloudXNS's local DNS optimization diagnostic tool. Just click this link to see your current broadband DNS IP on the page, as shown below:

The results above show your current IP and DNS IP. We just need to record this DNS IP. Then enter this DNS IP in the [IP whios query] of the webmaster tool to start the query to get the DNS exit IP shown in the following figure.

As indicated by the arrow above, it refers to the IP of your current DNS export, which is exactly an IP range. With this IP range, you can add these IP segments to the whitelist of your server's current firewall, so that you won't block the IP you log in to the server. Of course, this method won't work if you travel frequently.

In fact, this is at most a small trick, in fact, it is also supported by CloudXNS, which is used on private cables. Through the above IP acquisition process, you will understand what CloudXNS's private lines are for, and what is the use?

On how to collect local DNS export IP to share here, I hope the above content can be of some help to you, can learn more knowledge. If you think the article is good, you can share it for more people to see.
