The first reply seems plausible - I can't imagine any other cause, based on the information you've given so far. When in doubt about line terminations on input, I just do: 
s/\s+$//;  # instead of chomp

Apart from that, I have to ask: where does your input file come from? How confident are you that it would never contain something that you wouldn't want included in a shell command line?

If you were to add "-T" on the shebang line of your script, it would die rather than do  `host $host`, and with good reason.

Now, if you were to use a module, like Net::DNS::Nslookup (and there may well be others), you could get the IP addresses you want without having to run a shell command in back-ticks for each one. And you wouldn't need to worry about pesky little details like an input file that might contain shell-magic characters in the first column. Instead, your script could look like this: 

use strict;
use Net::DNS::Nslookup;

# ... do whatever you do open FH and load MYDB
#  (I'll fake it for now...)

my %MYDB = ( 'WWW.PERLMONKS.ORG' => 'TPF' );

while (<DATA>) {
    s/\s+$//;
    my @hostpair = split ' ';
    my $HOST = uc( $hostpair[0] );
    my $nslookup = Net::DNS::Nslookup->get_ips( $hostpair[0] );

    for my $addr ( split( /\n/, $nslookup )) {
        my ( $name, $ip ) = split( /,/, $addr );
        my $OWNER = ( exists( $MYDB{$HOST} )) ? $MYDB{$HOST} : "OTHER"
+;
        print "$hostpair[0]\t$ip\t$OWNER\n";
    }
}

Maybe that doesn't do exactly what you intended, and maybe you'd rather just use the command-line "host" utility - in that case, do be careful about your input...
