These need to be acknowledged. +If not the server will consider, on an individual basis, that the +client has disconnected and will +again update the databases to an offline state. + +Alternativelly the server may receive an OFFLINE_REQ packet from +the client, in which case the DNS record is updated at once and +the online state droped. |
