title: Meteor cluster, can I use IP address instead of sub domain for balancers?

  <pre><code>Making your instance a Balancer is pretty simple. Just export the following environment variable.
  
  export CLUSTER_BALANCER_URL=https://subdomain1.domainname.com
  export CLUSTER_BALANCER_URL=https://subdomain2.domainname.com
  </code></pre>
  
  <p>Can I use ip instead?</p>
  
  <pre><code>server1: export CLUSTER_BALANCER_URL=https://server1_ip
  server2: export CLUSTER_BALANCER_URL=https://server2_ip
  </code></pre>
