Methods and Arrangements for Activating IP Configurations
First Claim
1. A method of activating Internet Protocol (IP) configurations, the method comprising:
- maintaining a first IP configuration for an end node of an IP network;
maintaining a second IP configuration for the end node for IP communications directly between end nodes;
detecting a direct IP connection between the end node and another end node; and
activating the second IP configuration based upon the detection.

Abstract
Methods and arrangements for activating Internet Protocol (IP) configurations are contemplated. Embodiments include transformations, code, state machines or other logic for activating in an end node of an IP network 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 alternate embodiments, detecting a direct IP connection to another node may be accomplished by use of a spanning tree algorithm. 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. In still other embodiments, the suitable IP configurations may be activated under the control of BIOS. While specific embodiments will be described below with reference to particular circuit or logic configurations, those of skill in the art will realize that embodiments of the present invention may advantageously be implemented with other substantially equivalent configurations.
