title: Warning: Permanently added the RSA host key for IP address 'xxx.xx.xxx.x' to the list of known hosts
body: <p>I forked someone's repo and then got the warning in my terminal. I'm not getting the warning when I clone into forked repos from that user. </p>
  
  <p>I looked into the list here: <a href="https://api.github.com/meta" rel="nofollow noreferrer">https://api.github.com/meta</a> but couldn't find the IP address on there. Are there other places where I can verify whose IP address this is, and whether I should be concerned? Thank you!</p>
