You are not setting the variable $ip .

It seems to me you are confusing
Code:
while ip= read -r line

Code:
while IFS= read -r line

no?

although I suspect you may want to leave that out, since you are doing a word match with it and like this it will contain any spaces in the input file..

I don't know what the
Code:
echo " "

is for.. (it's not written to the log)

$ip_file could use a pair of double quotes although with the filename contained therein, this is not strictly necessary..

If you still can't get it to work, please post sample input files...
