Rewrite - forward server IP to domain url nginx

Question

I'd like to have the IP of my server be rewritten as a domain name url but I'm having the hardest time figuring out how to make this happen.

For example, when I enter 213.34.54.xxx in the browser, I'd like it to be rewritten as mydomain.com and NOT display the IP address.

My current configuration is as follows:

/etc/nginx/nginx.conf

user www-data;
worker_processes 2;
error_log  /var/log/nginx/error.log;
pid /var/run/nginx.pid;

events {
  worker_connections 1024;
}

http {
  include       /etc/nginx/mime.types;
  default_type  application/octet-stream;
  access_log /var/log/nginx/access.log;
  server_names_hash_bucket_size 64;
  sendfile        on;

  include /etc/nginx/conf.d/*.conf;
  include /etc/nginx/sites-enabled/mydomain;
}

/etc/nginx/sites-enabled/mydomain

upstream unicorn {
    server unix:/tmp/unicorn.mydomain.sock fail_timeout=0;
   }

    server {
      listen 80 default;
      server_name localhost;
      root /home/deployer/apps/mydomain/current/public;

      location ^~ /assets/ {
        gzip_static on;
        expires max;
        add_header Cache-Control public;
      }

      try_files $uri/index.html $uri @unicorn;
      location  / {
        proxy_set_header Host $http_host;
        proxy_set_header  X-Real-IP  $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header Host $http_host;
        proxy_redirect off;
        proxy_pass http://unicorn;
      } 

      error_page 500 502 503 504 /500.html;
      client_max_body_size 4G;
      keepalive_timeout 10;
     }

I've tried adding this to the server directive in mydomain configuration file:

rewrite ^ $scheme://mydomain.com$request_uri redirect;

but I get a TOO MANY REDIRECTS ERROR in my browsers.

At the very least, I'm able to prevent the IP address from being displayed by using this in the server directive:

if ($host !~* ^www\.) {
    rewrite ^(.*)$ http://www.$host$1 permanent;
   }

However, this is listed as one of the pitfalls on the nginx site :(

Any insights of what I might be doing wrong would be GREATLY appreciated!

Thanks!

Actually the answer above does not work (at least for me). I suppose since the question has been raised the asker has found his solution, but since I searched on google and a lot of links go here, maybe this solution will help other people, simply add this to your conf file:

server {
        server_name 162.13.171.178;
        # you can add other server_name if you need other IPs
        # or domain names such as without the www

        add_header X-Frame-Options "SAMEORIGIN";

        return 301 $scheme://www.example.com$request_uri;
}
