		fastcgi_param IP2PROXY_PROXY_AS		$ip2proxy_proxy_as;
		fastcgi_param IP2PROXY_LAST_SEEN	$ip2proxy_last_seen;
		fastcgi_param IP2PROXY_THREAT		$ip2proxy_threat;
		fastcgi_param IP2PROXY_PROVIDER		$ip2proxy_provider;
	}
}

Notes: Restart Nginx and view your server response header to confirm the variables are added.

Block Proxy IP
if ( $ip2proxy_is_proxy = '1' ) {
    return 444;
}
Block Spammers
if ( $ip2proxy_threat = 'SPAM' ) {
    return 444;
}

IPv4 BIN vs IPv6 BIN

Use the IPv4 BIN file if you just need to query IPv4 addresses.

If you query an IPv6 address using the IPv4 BIN, you'll see the INVALID_IP_ADDRESS error.

Use the IPv6 BIN file if you need to query BOTH IPv4 and IPv6 addresses.
