Why expensive ? Because address blocks are sold, not 'free'.
IPv4 address block ranges are hard to get and purchase. The Kindles do not (yet) use IPv6 networking (their Wifi connectivity provider AT&T does not (yet) support IPv6).
Also, you do not have to announce to Amazon whenever you get your clock set - - -
There is a KUAL.ntpdate button for that, using public NTP networks and/or servers - which allows the end-user to change from the defaults that it ships with.
Since these are **NOT** Amazon NTP servers, the ntpdate button works with the KUAL.firewall installed and the BBB filter enabled.
You might also want to checkout the KUAL.backdoor_lock application.
(I did not write that one - but it seems to be well thought out and well tested.)
