Methods and arrangements for activating IP configurations
First Claim
1. A method of activating Internet Protocol (IP) configurations, the method comprising:
- configuring an end node with a first and a second IP configuration for a network interface of the end node, wherein the first IP configuration includes a first IP address, the second IP configuration is suitable for IP communications between directly connected end nodes, and the second IP configuration includes a second IP address of the end node;
detecting a change in a connection of the network interface of the end node from a direct connection between the network interface of the end node and a first other node to a direct IP connection between the network interface of the end node and a second other node, the second other node comprising an end node, each direct IP connection via a cable extending from the end node to another node;
automatically switching from the first IP configuration for the network interface to the second IP configuration for the network interface, the switching comprising switching from the first IP address to the second IP address, the switching based upon the detection; and
communicating with the second other node through the cable extending from the end node to the second other node via the network interface and via the second IP configuration, the communicating using the second IP address.

Abstract
Methods and arrangements for activating Internet Protocol (IP) configurations are discussed. Embodiments include transformations, code, state machines or other logic for activating in an end node an IP configuration suitable for IP communications between the end node and another end node upon the detection of a direct IP connection of the end node to another end node. In some embodiments, the other end node may have a direct IP connect only to the end node. In some embodiments, the suitable IP configuration may involve a static IP address which has been published. In some embodiments, detecting a direct IP connection with another node may be accomplished by detecting a crossed-over Ethernet connection. In some embodiments, an operating system device driver may activate the suitable IP configuration. In other embodiments, an embedded system may activate the suitable IP configuration.
