Beginners, Nginx limit_conn_zone restrictions, please advise!

http{
    limit_conn_zone $binary_remote_addr zone=conn_zone:1m;
    server {
    listen       80;
    server_name  localhost;

    location / {
        root   /usr/code;
        limit_conn conn_zone 1;
        index  index.html index.htm;
    }
}

then

   nginx -t -c /etc/nginx/nginx.conf

   nginx -s reload -c /etc/nginx/nginx.conf

use

on another machine
ab  -n 30 -c 30   http://192.168.0.10/1.html

or

ab  -n 30 -c 30 -k   http://192.168.0.10/1.html

the result is the same, there is no limit on the number of connections, all are successful, and the conn_zone is not in effect in the error log.
