Yes, correct, except for the trailing dots.

Because ipsvd looks up a limited amount of file names in the directory,
and doesn't scan the whole directory on all incoming connections, such
files don't work.  If you want to have a single configuration for this
particular network, something like this could help

 touch .x.x.144.0:22
 for i in 4 5 6 7; do ln -s .x.x.144.0:22 x.x.14$i; done
