I figured out a solution in Perl. it's a little sloppy but it gets the job done.

Code:
#!/usr/bin/perl
use warnings;
$seperator = "===============================================\n";
$ping = "100%";
open MYFILE, ">ips.txt" or die $!;
while (defined($line = <>)) {
	print "$line\n";
	$line =~ s/^\s+|\s+$//g;
	chomp($line);
	my $nslookupOut = `nslookup $line`;
	print $nslookupOut;
		if ($nslookupOut =~ /NXDOMAIN/) {
    my $pingOut = `ping -c 1 -w 1.0 $line`;
	print $pingOut;
    if ($pingOut =~ /$ping/) {
		print MYFILE "$line is available.\n"
		}
	}
}
close MYFILE;
print $seperator;
if (open MYFILE, "ips.txt") {
	chomp(my @lines = <MYFILE>);
	foreach (@lines) {
		print "$_\n";
		}
	}

eof

eof(3tcl)						       Tcl Built-In Commands							 eof(3tcl)

__________________________________________________________________________________________________________________________________________________

NAME

       eof - Check for end of file condition on channel

SYNOPSIS

       eof channelId
_________________________________________________________________

DESCRIPTION

       Returns 1 if an end of file condition occurred during the most recent input operation on channelId (such as gets), 0 otherwise.

       ChannelId  must	be  an	identifier for an open channel such as a Tcl standard channel (stdin, stdout, or stderr), the return value from an
       invocation of open or socket, or the result of a channel creation command provided by a Tcl extension.

EXAMPLES

       Read and print out the contents of a file line-by-line:
	      set f [open somefile.txt]
	      while {1} {
		  set line [gets $f]
		  if {[eof $f]} {
		      close $f
		      break
		  }
		  puts "Read line: $line"
	      }

       Read and print out the contents of a file by fixed-size records:
	      set f [open somefile.dat]
	      fconfigure $f -translation binary
	      set recordSize 40
	      while {1} {
		  set record [read $f $recordSize]
		  if {[eof $f]} {
		      close $f
		      break
		  }
		  puts "Read record: $record"
	      }
