list the current machines ip address(es),
or expand a short ip for use in further commands.
a short ip can be given like 100, .100, .2.100

options
   -first  show just the first ip of all ips
           which are not localhost.
           default since sfk 1.9.6.2 is to
           show all ip's, if not filtered by
           environment variables (see below)
   -all    show all ip's, ignoring any given
           environment variable

environment variables
   multiple network interfaces will display
   multiple ip's. to filter or predefine the
   output of 'sfk ip' you can use:

   set SFK_OWN_NET=192.168.1
      to define your preferred subnet.
      e.g. if your computer has ip's
         192.168.56.1
         192.168.1.100
      then 'sfk ip' will select the 2nd address.

   set SFK_OWN_IP=192.168.1.100
      to define your machine's IP manually,
      for calls to 'sfk ip' within batch files.

chaining support
   output chaining is supported.
