Field comparing in files

Guys
trying to compare field in two files.

For Ex:
demo.txt
23.33.4.2 hostname
3.2.4.2 hostname12

demo1.txt
3.3.3.3 hostname23
45.23.23.23 hostname 323

I would like to compare the ips b/w these two files.any suggestions..if two ips match it should say not usable else usable.

Thanks
Cool

Code:

awk '{
   if (x[$1]++)
      print "Not usable "$1
   else
      print "Usable "$1
}' demo.txt demo1.txt
