For what reason internet provider changes your IP address?
Why would someone want to change his IP address, expect that he just wants remove IP ban?
What are the specific cases or under what circumstances provider changes your IP address?
I would like to know what would it solve.
The IP is changing because of the lease time set up in the Netgear router in the DHCP settings. IP adresses in a DCHP network are dynamic. The IP adress may change every time you connect and disconnect to the network. Changing IP can keep our data safe from hackers.
You guys are missing the most important reason why your ISP changes the IP address (besides that utilizing DHCP maintains a robust network), they can charge you am extra 30 bucks a month for a static ip address (so you can be your own host).
