Claim Text:
1. A method for sharing an Internet Protocol (“IP”) address between geographically distant locations and redirecting IP traffic instantly to desired locations in a system, comprising: advertising, from a distribution point, a route for the shared IP address to the Internet through an external routing protocol; performing, by the distribution point, a first stateless Network Address Translation (“NAT”) conversion of traffic having the shared IP address as a destination to a local network IP address within a datacenter where a device using the shared IP address is running; performing, upon arrival at the datacenter, a second stateless NAT conversion from the local network IP address to the shared IP address, restoring the traffic to its original form, and passing the traffic to a device processing requests using the shared IP address for the traffic, wherein the device processing the requests using the shared IP address responds directly to an originator of the traffic through a standard network, and the reply does not need to be modified or subject to any conversion; and coordinating mapping between the shared IP address and local networks to create stateless NAT rules in the distribution point and end points to redirect the traffic to the desired locations.
