I disclosed my IP address on an apple support page when I was trying to get help with a network problem, do I need to worry?
Probably not, but it's pretty easy to change your IP address. Just leave your router unplugged overnight.
you have to login the modem/router .if you do not know how to do that you might wanna contact verizon to find out the login info. on my actiontec gt784 it is under
LAN IP And DHCP Settings lease time mine goes from a week to one day
