I see that you've gotten a couple of answers already.  However, in the 
interests of "There's more than one way to do it", here's another approach:

 grep truc /etc/hosts | grep -o 
"[0-9]\{1,3\}\.[0-9]\{1,3\}\.[0-9]\{1,3\}\.[0-9]\{1,3\}"

or

grep truc /etc/hosts | grep -o "[0-9]*\.[0-9]*\.[0-9]*\.[0-9]*"

or

grep truc /etc/hosts | cut -f1 -d" "

I'm sure that there are others. :)
