Claim Text:
1. A method comprising: establishing a network connection between a first information handling system (IHS) and a second IHS, the first and second IHSs including respective interfaces, the network connection being a network connection that uses a first protocol version that employs subnets or a second protocol version that employs prefixes; receiving, from the first IHS by the interface of the second IHS, a proposal including subnet information related to the interface of the first IHS if the network connection is employing the first protocol version for the network connection, wherein the first IHS includes a first virtual IP address (VIPA) that exhibits an address other than an address in the subnet of the interface of the first IHS if the network connection is employing the first protocol version for the network connection; receiving, from the first IHS by the interface of the second IHS, a proposal including prefix information including a list of prefixes related to the interface of the first IHS if the network connection is employing the second protocol version for the network connection, wherein the first IHS includes a first virtual IP address (VIPA) that exhibits an address other than any address in the prefixes of the interface of the first IHS if the network connection is employing the second protocol version for the network connection; determining, by the second IHS, subnet information or prefix information related to the interface of the second IHS that receives the proposal; testing, by the second IHS, to determine if the subnet information of the interface of the second IHS matches the subnet information of the interface of the first IHS or the prefix information matches at least one prefix of the list of prefixes; and qualifying, by the second IHS, the network connection to employ a particular protocol if there is a match between the subnet information of the interface of the second IHS and the subnet information of the interface of the first IHS or there is a match between the prefix information of the interface of the second IHS and at least one prefix of the list of prefixes, and otherwise disqualifying the network connection from using the particular protocol if there is no match, wherein the particular protocol is a shared memory communications over remote direct memory access protocol.
