When we said that IP addresses were uniquely identifying each device, this was a bit of a stretch. In reality, IP addresses uniquely identify a device within a given context. Consequently, IP addresses need only to be unique within this context. The Internet is such a context but not all computers accessing the Internet need to be directly connected to it. ![]() Most users access the Internet through some sort of gateway and use local IP addressing, internally. In these situations, only the local addressing has to be unique and it’s not uncommon to have identical IP addresses used in different organizations. Take, for example, your typical home Internet WiFi router. Most of them have 192.168.0.1 as their internal IP address. That specific address is therefore present on most home networks. The very first step in planning a network in all but the smallest networks is preparing an IP addressing plan. The idea behind the plan is to define how IP addresses are going to be used. For instance, a range of IP addresses will likely be reserved for servers. ![]() Some will obviously be assigned to computers connected to the network. And of course, IP addresses will be reserved for other devices such as networking equipment or network-connected printers. This task is often done using simple tools such as spreadsheet software. The next task is assigning IP addresses to devices. This is what we refer to as IP address allocation. ![]()
