title: Strange IP when trying to yarn start - EADDRNOTAVAIL
body: <p>I have a fairly fresh install of OpenSUSE installed on my laptop and was trying to test out a brand new React application.</p>
  
  <p>I ran the following commands from the create-react-app site:</p>
  
  <pre><code>    npx create-react-app my-app
      cd my-app
      yarn start
  </code></pre>
  
  <p>When this happens, I get the following output in my terminal</p>
  
  <pre><code>yarn run v1.15.2
  $ react-scripts start
  Attempting to bind to HOST environment variable: linux-wjcv
  If this was unintentional, check that you haven't mistakenly set it in your shell
  
  Could not find an open port at linux-wjcv
  Network error message:  listen EADDRNOTAVAIL 92.242.140.2
  
  error Command failed with exit code 1.

  <p>I confirmed that linux-wjcv is my computer name, but I'm not sure where that 92.242.140.2 IP address is coming from. A quick google search tells me that IP is located in Ireland, which is nowhere near me.</p>
  
  <p>I did a quick look at my hosts file in /etc/hosts and everything I see is going through 127.0.0.1. So I'm not sure where this IP is coming from, or why a fresh application would try to use it.</p>
  
  <pre><code>127.0.0.1   localhost
  
  # special IPv6 addresses
  ::1         localhost ipv6-localhost ipv6-loopback
  
  fe00::0     ipv6-localnet
  
  ff00::0     ipv6-mcastprefix
  ff02::1     ipv6-allnodes
  ff02::2     ipv6-allrouters
  ff02::3     ipv6-allhosts
  </code></pre>
  
  <p>My apologies if this is a dumb question. I'm still pretty new to running a Unix OS.</p>
