Why doesn't my Android tablet surrender the IP address?

[AC Question]

Android tablet does not surrender IP address.

Every time I log onto home wifi my tablet gets a new IP address and doesn't release the old one. Verizon console shows about 70 addresses for android with the active one being 192.168.1.83 Two iphones, two kindles and a laptop each claim only one.
Using 4.4.2 on A88X from alldaymall. Doesn't seem to cause a problem at the moment but what happens when it gets to several hundred IP addresses?

You need to consult a Technical Guy for that.

Thanks RogMoore, I spoke with three verizon and one alldaymall techs--no joy.
I reset the modem which cleaned up the unused addresses but new addresses are still being added.
That will manage the problem but not solve it.
