You may need to Listen multiple IP addresses to be served for a domain, just add like following configuration.

Open a nginx.conf file by text editor vim or vi,

#  vim /etc/nginx/nginx.conf

server {
          access_log /var/log/nginx/logs/access.log combined;
          error_log /var/log/nginx/logs/error.log warn;

Once configured on file restart your NGINX server,
# /etc/init.d/nginx restart

Note : If you are managing mutliple virtual hosts on nginx server configure on that file.
