It means there is no reason to deny to have immobile home agents.

Not at all, because a DNS client has no idea when its peer, a
mobile host, changes its location.

Assuming a mobile host changes base stations every 5 seconds
(moving at 144km/h with cell diameters of 200m) and old base
stations are still usable within 1 second after the changes,
a DNS client must check DNS servers every 0.5 second (reserving
0.5 second for RTT and possible retry).
Can you still say it almost perfect?
