>When your router receives a non-static DHCP assigned IP address from your ISP there is a pre-defined time limit built into the assignment, this time limit is called a DHCP Lease. The typical lease time for ISP’s in the United States is roughly 7 days. However in most instances your router will renegotiate this lease prior to its expiration. During the lease renegotiation, it is very common for the same IP to be reassigned to your router. In fact our research has discovered many homes that have theoretically dynamic IP’s, but have held the same IP for multiple years. Because of this recursive reassignment the typical location targeted by El Toro has held the same IP address for 7 months.
It seems a typical location has the same ip address for around 7 months and can indeed have the same address for far longer if your service isn't interrupted, you don't change or reboot networking hardware, and you don't try to connect to the game from your laptop at your friends house.
