title: How do I get the IP address of an erlang node?
body: <p>Is there a simple way to get the IP address of a connected erlang node? I'd like to initiate a SCTP connection with a few nodes and due to the way the system is engineered, the knowledge I have about them is just their node() atom.</p>
  
  <p>More precisely, I am wondering if there is some API provided by Erlang (or some derived technique) that allows to obtain a node's IP address given its identifier atom().</p>
