Perhaps a bit of Perl?

Code:

#!/usr/bin/perl
# finn.report.pl

# these two statements help detecting bugs
use strict;
use warnings;

my %dates; # to keep a record by dates

# read the file given at the command line
while(<>) {
    # extract date and ip, disregard rest 
    my ($day, undef, $nbits, undef) = split; 
    # extract ip bits wanted
    my ($netbits) = $nbits =~ /^(\d+\.\d+)/;
    # increase count of ip bits
    $dates{$day}{$netbits}++;
}

# report back to stdout
for my $d (sort keys %dates){
    print "IP total counts for $d\n";
    for my $ipp (sort keys %{$dates{$d}}){
        printf "%-8s = %s\n", $ipp, $dates{$d}{$ipp};
    }
    print "\n";
}

Run as

Code:

$ perl finn.report.pl finn.file 
IP total counts for 02/Sep/2015:
11.151   = 1

IP total counts for 03/Sep/2015:
11.14    = 1
11.151   = 3
11.152   = 1
11.188   = 2
