<p class=MsoNormal>Hello,<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I have a little application which contains both a client and
a server. The client attempts to connect to the server using an address
resolved with <span style='font-size:8.0pt;font-family:Consolas;color:#010001;
background:silver;mso-highlight:silver'>enet_address_set_host</span><span
style='font-size:8.0pt;font-family:Consolas;color:#010001'> to which I give
with my PC’s name as shown by ipconfig /all</span>. Now, it happens that
I also have a video capture device plugged on the PC, which for some reason
creates a virtual network :<o:p></o:p></p>

<p class=MsoNormal>The problem is that this address comes first in hostEntry,
thus causing the client to attempt to connect to the video device (I suppose).
I have come up with a very dirty trick to select the address I am interested
in, but maybe someone will have a more portable solution ?<o:p></o:p></p>
