255.255.255.255 automatically selects the "best" HA for you. If you look at the programing for Verizon phones, they use 255.255.255.255 also. It is actually awesome that they do that now. When you have a NY number and you go to LA, it will use LA's HA, and not have to route all traffic through NY. Unlike if it has the NY HA as it's primary. The secondary HA is usally the HA close to the phone number that Sprint gives you. That way if 255.255.255.255 doesn't provide a good HA, you have a backup.
