<p dir="ltr">jndn currently supports localhost prefix registration only.<br>
NFD treats loopback address as localhost. 192.168.1.9 is not a loopback address despite that it's on same machine.<br>
A localhost registration, when sent to a non-local face, will be silently rejected.</p>
<p dir="ltr">It's intentional for NFD to interpret non-loopback address of same machine as non-local, <span style="background-color: rgb(255, 255, 0);">otherwise proxy app for new socket type or wire format won't be able to create a non-local face without requiring a separate machine.</span></p>
