Yes. Icecast supports all operations on all sockets.

It's a bad idea to use IP addresses. If at all, you should add a DNS
record for it in your internal DNS zone.

This depends on your version. With Icecast 2.4.x (stable) it is mostly
possible. With Icecast 2.5.x (development) it is possible but requires
some configuration.

The big point here is: Why are you trying to do this?:
      * Mounts can be set as hidden so they are not listed. If listing
        mounts is the problem.
      * If you don't like the public WI at all, just point your
        <webroot> to an empty directory. You can also modify the XSLT
        files to match your needs.
      * The admin interface can be secured using a secure password. This
        will make keep it available and secure.
      * Hiding the version number: Doing this makes it harder for
        debugging. However it does not improve security at all (as many
        think) as you can fingerprint the version number anyway.
      * The authentication system can be used for precise access
        control. (This is even more true for Icecast 2.5.x).


With best regards,
