DENY ALL ONLY ACCEPT SOME IP

Hello,
If it is possible to add some on default.conf that i can deny all from my page and only allow some IP?

Here is my default.conf but I dont know how I need to do...

server {
set $rootpath "/var/www/ipmp";
root $rootpath;
listen 80;

if ($request_uri ~ (/).*) {
rewrite ^ https://$host$request_uri? permanent;
}
if ($request_uri ~ (/mobile/).+) {
rewrite ^ https://$host$request_uri? permanent;
}
if ($request_uri ~ (/interactive/).*) {
rewrite ^ https://$host$request_uri? permanent;
}

include /etc/nginx/part.d/*.part;
}
server {
set $rootpath "/var/www/ipmp";
root $rootpath;
listen 443 ssl;
keepalive_timeout 70;

server_name $host;
ssl_certificate /ha_shared/ipmp/config/certificates/cert.csr;
ssl_certificate_key /ha_shared/ipmp/config/certificates/cert.key;
ssl_protocols SSLv3 TLSv1 TLSv1.1 TLSv1.2;
ssl_ciphers HIGH:!aNULL:!MD5;
ssl_session_cache shared:SSL:20m;
ssl_session_timeout 10m;

include /etc/nginx/part.d/*.part;
include /etc/nginx/part.d/onlyssl/*.part;
}

Where I need add that deny all? That is my root path: /var/www/ipmp . Hope some can help.
