enumerating ipv4 and ipv6 address of my cards using boost asio

Question

I am trying to enumerate ipv4 and ipv6 addresses of all the network cards(I have 2 cards) my pc.

I am using the following code to do that.

using boost::a         


        

Answer 1

If the platform is Windows 7 SP1 the link-local interfaces are being skipped as they are tagged "SkipAsSource" by Windows which means that getaddrinfo will not return them and hence neither will Boost.

You can try to inspect the flag with the following command:

netsh int ipv6 show addresses level=verbose

Address fe80::e0:0:0:0%14 Parameters
---------------------------------------------------------
Interface Luid     : Teredo Tunneling Pseudo-Interface
Scope Id           : 0.14
Valid Lifetime     : infinite
Preferred Lifetime : infinite
DAD State          : Deprecated
Address Type       : Other
Skip as Source     : **true**
