IOS ---------- how to check whether the domain name supports ipv6, ios ---------- ipv6

1. Check the databases you use, such as af 3.0 or above (you don't need to modify them). Search for other libraries to see if ipv6 is supported.

2. Make sure that the sdk you use supports ipv6. Just read the document.

3. Terminal dig + nocmd + nostats your domain name AAAA this is to see if your server has responded in ipv6. (This is what others taught me. Thank you very much)

 

This is A short book. Check that in a is ipv4, And the Got answer has A status: no error. Generally, if the status is no error, no error is returned. You can also check the servers of the recently launched projects.

If there is an error, it corresponds to the following table:

If there is a problem with our dns, status is the third one...

Conclusion: as long as the library is supported and the sdk is no problem, if there is no problem in ipv6 built on mac, it basically has nothing to do with our iOS front-end. Most of them are server-related.
