Stuck with while loop

I have a tmp directory with some files in it. I need to parse these file names and then proceed to parse the contents of each one.

!/bin/bash

TMPDIR=/home/david/tmp
     ip_targets(){
        while IFS= read -r file_name; do
            echo "This is: $file_name"
                while IFS= read -r ip;do
                        echo "This is IP: $ip"
                done < <(cat "$file_name")  ## Is this wrong ?
        done < <(find "$TMPDIR" -regex '.*.vms$')
     }
     ip_targets

How can I achieve this ? The above allows $file_name to be echoed but not the contents of it.

Try this:

!/bin/bash

TMPDIR=/home/david/tmp
     ip_targets(){
        while IFS= read -r file_name; do
            echo "This is: $file_name"
            grep -woE "\b([0-9]{1,3}\.){3}[0-9]{1,3}\b" $file_name    
        done < <(find "$TMPDIR" -regex '.*.vms$')
     }
     ip_targets
