Ralph Goers commented on LOG4J2-3094:
-------------------------------------

Well, you can create an appender to do almost anything you want. You just have 
to figure out how.

I don't really understand what it means to have dynamic hosts and ports. How 
would the appender have any idea how to connect to them?  While the 
TcpAppender, which the SocketAppender extends, does not support "dynamic" hosts 
and ports, it does support providing a host name that is defined by DNS. If 
that resolves to one or more ip addresses  the appender will use them. But it 
will only use 1 at a time and fail over to the others whenever the connection 
fails.
