Peanut Shell domain name experiment [personal notes, for reference only]

1. Desktop (Wireless disabled, wired dialing)

Bind the free oray domain name and the dial-up IP address (change the record ).

2. The oray client is updated in time, but the ping domain name times out.

The reason is that the binding has not been updated by the system. (Where does the system refer to DNS or other devices ?)

3. Restart oray and the ping still times out.

4. restart the computer,

The dial number is still the last IP address. You can ping the local Ping domain name !!

Advanced:

1. Connect the laptop to the server wirelessly. Ping the domain name. You can ping the server!

The desktop enables Windows Firewall, and the laptop can still be pinged.

Further advanced:

How does oray bind a dynamic IP address?

1. Bind two public IP addresses (server dialing and desktop dialing) to the record ),

After the restart, the third-party (LAPTOP) can ping the domain name.

Failed: the IP address changed after the desktop dialing

2. Activate oray and clear the record.

The Ping times out on both the host and laptop, and the ping from the laptop restarts. The Ping still times out.

Server Ping timeout (resolved to the IP address in the previous a record)

Why: Does the PC cache domain name and IP address records?

Restart the reset PC (the PC where the oray client is located), and ping the client again.

Total cause: the domain name for activating oray does not point to the IP address obtained from the local dialing!

The oray official website explains that ISP has implemented Nat forwarding. oray domain name resolution points to the ISP's gateway. oray's solution is only for professional users. In other words, if you want to solve the problem, pay the first !!

Final Conclusion: oray can be free of charge for binding static public IP addresses

If you want to bind Dynamic IP addresses for free, use other software! (The crux of the problem is that these software is resolved differently from the local machine, and Google may have known that the ISP has given Nat)
