perl -pe -i s/xxxxxxxxxxxxx/xxx.xxx.xxx.xxx/g filename

Two alternatives. The first keeps things in the shell and is the most efficient:

while read line
do
var1=${line%????????}
var3=${line#????????}
var2=${line%$var3}
var2=${var2#$var1}
echo "${var1}.${var2}.${var3}"
done < filename

The second uses awk:

awk '{print substr($0,1,4} "." substr($0,5,4} "." substr($0,9)}' filname
