[REBOL] Re: Commander.c adds Shell access for Rebol

From: athena:pop3-dfw:myfirstlink at: 24-Mar-2001 10:35 has special attributes in the IP network. It is not assigned to anyone so it can not be routed in the Internet except by default routes nor can it get out of a router since no network interfaces are configured with this address. On the local LAN, potentially could be directed to a specific machine, but you have bigger problems than an attack on your machine if it is coming from your internal network. Systems should always assume that 127.x.x.x is destined for itself so it should be very difficult to get a 127.x.x.x packet onto even the local network. For internal machine communication between socket based applications does not pose a serious threat. The real issue is activation of the TCP or UDP port on which you intend to communicate. Any system that can get to your machine can access the port. The "server" end of the connection should verify that the "client" end is and reject any other connections from other IP addresses.
