Check if server is accessible via IPv6?

Question

是否可以通过c＃检查服务器是否可通过IPv6访问？

Answer 1

遍历从Dns.GetHostEntry返回的地址列表，并检查是否有任何IsIPv6xxxx属性设置为true

Answer 2

It depends on what you mean - if you know (or can resolve) the server's hostname or DNS name to an IPv6 address, it should be possible for you to do a couple of things.

You could either send a test packet using IPv6 to the server and see if you get a response back. Alternatively, if you're going IPv6 all the way, you could change your own network layer to be IPv6 only. On newer releases of Windows server I believe you can switch IPv6 on and IPv4 off.

Hope that helps!
