172
If this option is used, the server will only listen to a

174
an IPv4 address can be specified using the
175
<quote><literal>::FFFF:192.0.2.3</literal></quote> syntax.
176
Also, if a link-local address is specified, an interface
177
should be set, since a link-local address is only valid on
178
a single interface. By default, the server will listen to

all available addresses.

to be changed this if it, for some reason, is necessary to
242
run more than one server on the same

<emphasis>host</emphasis>, which would not normally be
244
useful. If there are name collisions on the same

<emphasis>network</emphasis>, the newer server will
246
automatically rename itself to <quote><literal>Mandos
