+<h2> Frequently asked questions </h2>
+</div>
+
+<h3> I want my web server to listen to more than one address. Do I need
+to do all that for every address I have? </h3>
+
+<p>
+ Not necessarily: you could listen to <tt>0.0.0.0</tt> for IPv4, and
+<tt>::</tt> for IPv6. But if you don't want your server to listen to
+<em>all</em> the addresses on your machine, then yes, you will have
+to run one process per address:port tuple.
+</p>
+
+<p>
+ It's okay though: every listening process is very small. The skarnet.org
+server has two network cards and runs a web server on both of them, on
+IPv4 and IPv6, over HTTP and HTTPS, which makes 8 services. Plus one
+<a href="//skarnet.org/software/s6/s6-log.html">s6-log</a> logger process
+for each of these services. Plus a supervisor for every service and every
+logger &mdash; for a whooping total of 64 long-running processes just for
+its web server functionality; and it's still not even noticeable, the
+amount of resources it consumes is negligible. So, don't worry about it.
+</p>
+
+<p>
+ Note that this allows you to run different instances of
+<a href="tipideed.html">tipideed</a> with different configurations, if
+you need it. Use the <tt>-f</tt> option to specify a different config
+file for <a href="tipideed.html">tipideed</a>.
