Abstract:
1. A computer executed method of determining an order of a plurality of source network addresses of a computing device to be advertised to enable a higher probability that an advertised source network address of the computing device is accessible, the method comprising: determining a primary network connectivity mode for a network port of the computing device, the primary network connectivity mode being a most preferred connectivity type for the network port having full connectivity; determining a primary network address connectivity mode for the network port is firewall traversal, and based on the determination of the primary network address connectivity mode being firewall traversal: determining the primary network address connectivity mode for the network port is Teredo, and based on the determination of the primary network address connectivity mode for the network address being Teredo: determining the primary network address connectivity mode for the network port is native or 6to4, and based on the determination of the primary network address connectivity mode being native or 6to4: determining the primary network address connectivity mode for the network port is not one of firewall traversal, Teredo, native or 6to4, and based on the determination of the primary network address connectivity mode for the network port as not being one of firewall traversal, Teredo, native or 6to4, generating an error indicating no connectivity mode for the network port.
