Dynamic domain name resolution [personal notes, for reference only]

Use meibu instead of oray

1. register an account on the official website and download the meibu client for installation.

2. log on to the client, ping the test, and time out.

Cause: the local IP address obtained by the software is vm8 IP, and the resolution IP address starts with 61.

Ping again after vm8 is disabled. Timeout.

(Oray is also the reason for vm8, not tested)

The problem occurs. What public IP is obtained by dialing ?! But why is the IP address of the Local Machine on Baidu starting with 61? Nat now?

Discard meibu, with www.no-ip.com

1. Download the client (Windows or Linux)

2. Ping test. Based on the above results, the IP address resolved during Ping is still starting with 61.

3. After the IP address is bound to a dial-up IP address, ping the IP address.

Conclusion:

After being bound to a dial-up IP address, Ping

However, IP addresses starting with 61 are dynamically parsed,

The crux of the problem is what is the relationship between the IP address obtained by dialing and the IP address starting with 61 (what is the relationship between ISP and Nat ?)

None of the above software meets my requirements and I still cannot find a dynamic binding solution.

 

 

Next step:

The DNS configuration in Ubuntu maps the local IP address and domain name, and uses the configured DNS resolution during access (what is the DNS address? Is it still accessible public IP? In this case, the IP address of the DNS server is dynamic after dialing! I still cannot solve the problem, but I understand the principle of DNS configuration ).

 

Can this be done? in Linux, write a boot script to execute the script to obtain the dial-up IP address, and then bind the IP address to the DNS and update it (indirectly implementing dynamic resolution ), problems to be Solved here: 1. The use of the dialing software in Linux (currently not supported, try other solutions); 2. the parsing software can be no-IP, oray

 

It seems that the problem has been solved. As long as the dial-up software in Linux can be used, and the software supports binding the IP address obtained by dialing on the Linux command line interface, the entire 219 (in school ?) You can access the FTP through the domain name.

The following solutions: 1. Use of dialing software in Linux; 2. Use of oray in Linux.
