</div></div>Thanks to everyone on helping to clarify this. I'd suppose relatively<br>
few users have more than one network card? ;-)<br>

<br>I agree: the message could be more clear. Why not replace <a href="http://0.0.0.0">0.0.0.0</a> with "<all interfaces>"?<br><br>Or, perhaps, 'hg help serve' could document -a's default as "(default: all interfaces)"<br>
