well, perl to the rescue:

Code:
#!/usr/bin/perl
open MYFILE, $ARGV[0] or die $!;
while (<MYFILE>) {
chomp;
#perform work here
($field1,$field2,$field3,$field4,$field5,$field6,$field7,$field8,$field9,$field10,$field11,$field12,$field13) = split(' ');
if ($field10 eq "host" and $field8 eq "host") {
   my $srcip = `dig +short -x $field9`;
   my $dstip = `dig +short -x $field11`;
   chomp $srcip;
   chomp $dstip;
   print "$field1 $field2 $field3 $field4 $field5 $field6 $field7 $field8 $field9($srcip) $field10 $field11($dstip) $field12 $field13\n";
   } 
elsif ($field8 eq "host" and $field10 ne "host") {
   my $srcip = `dig +short -x $field9`;
   chomp $srcip;
   print "$field1 $field2 $field3 $field4 $field5 $field6 $field7 $field8 $field9($srcip) $field10 $field11 $field12 $field13\n";
   } 
elsif ($field10 eq "host") {
   my $srcip = `dig +short -x $field11`;
   chomp $srcip;
   print "$field1 $field2 $field3 $field4 $field5 $field6 $field7 $field8 $field9 $field10 $field11($srcip) $field12 $field13\n";
   }
else { 
   print "$field1 $field2 $field3 $field4 $field5 $field6 $field7 $field8 $field9 $field10 $field11 $field12 $field13\n";}
   }
close (MYFILE);

you put your input file on the command line as an argument. If the word 'host' appears in certain locations, then the next field is assumed to be an IP address. The script then prints the line, with the resolved IP in parenthesis after the raw IP. Obviously, you can redirect output to stdout or to a file.

Not elegant, but it seems to work Smilie
