A system, a method, and a computer program product for providing a high availability internet protocol address are disclosed. At a first customer routing domain, a high availability internet protocol (“HA IP”) address is generated and configured on a first computing device located within the first customer routing domain. The HA IP address is forwarded to a second computing device located within at least one of the first customer routing domain and a second customer routing domain. The forwarded HA IP address is configured on the second computing device. The second customer routing domain is connected to the first customer routing domain using a transport mechanism. The first and second computing devices can be configured as a host for providing a communication capability to the customer routing domains based on the high availability internet protocol address.
