Hello.
How can I grep IP-addresses from a file "ip.txt" and only get the IP that is an exact match?.

"ip_host.txt" is the file with the IP that I want to grep from the file "ip.txt".
I want 4 matches, not 9 matches.

ip_host.txt
192.168.1.1
192.168.1.2
192.168.1.3
192.168.1.55



ip.txt
a,192.168.1.1
b,192.168.1.2
c,192.168.1.14
d,192.168.1.3
e,192.168.1.15
f,192.168.1.20
g,192.168.1.19
h,192.168.1.22
i,192.168.1.55
j,192.168.1.59
k,192.168.3.15



The code:
$file = "ip.txt";
open(LOG, $file);
chomp
(@ip = <LOG>);
close LOG;


$file_host = "ip_host.txt";
open(LOG, $file_host);
chomp
(@ip_host = <LOG>);
close LOG;


foreach $host (@ip_host) {

@grep = grep /$host/, (@ip);

foreach $x (@grep)
{
print "$x\n";
}
}
