This allows data being sent over a network to know where it’s going and where it came from… it’s a virtual address. Although, what I thought was pretty cool was how there are two different types of IP addresses, Dynamic and Static.  The key differences are that dynamic changes after a period of time, are automatically assigned by the networks DHCP, and a typically more common with ISPs and home networks. Whereas a static IP address is permanent, manually ...
