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

NAME
dxsetacl - Graphical interface for setting the ACL on a file or directory SYNOPSIS
/usr/bin/X11/dxsetacl [arguments...] OPTIONS
The name of the file or directory to operate on. The regular X resources can be supplied to dxsetacl on the command line. DESCRIPTION
The dxsetacl command provides a graphical interface for examining and setting file access control lists (ACLs). If a path is specified on the command line, the file system object represented by path is used as the target of the command. In addition, there is a Find Object area on the main dialog box. A path may be typed in, or located by browsing the file system. A file reference may be dragged from a CDE application, such as the File Manager, and dropped on the Find Object area. Once an object is selected, its full path name, object type, owner, and group are displayed along with the ACL. The ACL is displayed, one entry per line, in a list widget. Clicking on an entry selects it. Double clicking on an entry or selecting the Change Entry button brings up a dialog that allows the fields of the entry to be modified. Clicking on the Delete Entry button removes the entry. The owning user, owning group, and other user entries may be modified but not deleted. (See acl(4) for more information.) The New Entry button may be used to create a new group or user entry. If the object is a regular file, device special file, or UNIX domain socket, it only has an access ACL. If the object is a directory, it has an access ACL, a default access ACL, and a default directory ACL. Which ACL of a directory is being edited may be selected with a radio button. Note The dxsetacl command will show and set ACLs on file system objects, regardless of whether ACLs are used by the system for access decisions. The sysman secconfig utility is used to enable ACL checking. SEE ALSO
