Guys got this resolved finally. Spaces were a problem with IP address catch. Removed spaces from both ends (left and right) 

#!/usr/bin/perl
use strict;
use warnings;
use Acme::Tools;
use Data::Validate::IP qw(is_ipv4);

print "Enter the absolute directory location for ifcfg files\n";
my $directory = <>;
chomp($directory);

opendir(DIR, $directory) or die "couldn't open $directory: $!\n";
my @ifcfg_files = grep { /^ifcfg-bond/ } readdir(DIR);
closedir DIR;


foreach (@ifcfg_files) {

my %hash = ();
my $file = "$_";

open (my $fh, "<", $file) or die "Can't open the file $file: ";


while (my $line =<$fh>)
{
    chomp($line);
    next if $. <= 2; # Added '='
    my($key, $parameter_value) = split("=", $line);
    next if $key eq "BONDING_OPTS";
    $parameter_value =~ s/^\s+|\s+$//g;
    if ( lc "$key" eq lc "ipaddr" )
    {
      if (is_ipv4($parameter_value))
      {
        print "Yes";
      }
    }
}

} #Outer Foreach

Result
[root@localhost bond]# perl ifcfgbondverification.pl 
Enter the absolute directory location for ifcfg files
/root/office/ifcfgverification/bond
YesYesYesYesYesYesYes[root@localhost bond]#
