+Do you need virtual hosting
+VIRTUAL_HOST
+  This is only needed when you want to run two or more servers on the
+  same machine and on the same port (but different devices).
+  In general you will only need this if you have at least two ethernet
+  cards in your machine with a different IP-number.
+  If you specify 'y' here, then you can "bind" a server to one of your
+  interfaces.  You should use the command line option '-w' to tell the
+  server to which interface to bind to.  No error is reported if this
+  fails, the server will simply not run.
+  If no '-w' option is given then the server name specified in the
+  'M: line' of the "ircd.conf" file of the server is used, provided it
+  resolves to an IP-number of one of your interfaces.  Note that
+  normally the name does not have to resolve, but when you define this,
+  it MUST resolve or you must use the -w command line option, or the
+  "bind" will fail.
+  If you are unsure, specify 'n'.

+NODNS
+  If you are playing with the server off-line, and no DNS is available, then
+  long delays occur before the server starts up because it tries to resolv
+  the name given on the M:line (which usually isn't given in /etc/hosts) and
+  for each connecting client.
+  If you specify 'y' here, then a call to gethostbyname() will be done only
+  for the real hostname, and the server will not try to resolv clients that
+  connect to `localhost'.
+  Note that other calls to gethostbyname() are still done anyway if you
+  use VIRTUAL_HOST and that the server still tries to resolv clients
+  that connect to the real IP-number of the server.
