A router can assign 192.168.0.2 or 192.168.0.3 to any device on a local network automatically, or an administrator can do it manually. Both of these IP addresses are private IP addresses, meaning that these can be accessed only from within a private network and not from the outside, like from the internet. For this reason, these IP addresses don't need to be unique from network to network, like how a public IP address must be different across the entire internet. Lifewire / Luyi Wang Why Are These Addresses so Common? 192.168.0.2 and 192.168.0.3 are commonly used on private networks because many routers are configured with 192.168.0.1 as the default address. A router with a default address of 192.168.0.1 typically assigns the next available address to the devices in its network. For example, if your laptop is the first device that connects to your home network, then it will likely receive an IP address of 192.168.0.2. If your tablet is next, the router will likely give it the 192.168.0.3 address, and so on. However, the router may use 192.168.0.2 or 192.168.0.3 if the admin chooses. In cases like that, where a router is assigned an address of 192.168.0.2, then the first address it gives out to its devices is typically 192.168.0.3, and then 192.168.0.4. How 192.168.0.2 and 192.168.0.3 Are Assigned Most routers automatically assign IP addresses using DHCP so that the addresses can be reused as devices disconnect and reconnect. A router with an IP address of 192.168.0.1 can assign its devices an address within the range of 192.168.0.1 to 192.168.0.255. Usually, there's no reason to change this dynamic assignment, and it takes the burden off the network administrator to manually give out addresses. However, if a conflict arises in IP assignment, you can access the router's administrative console and assign a certain IP address to a certain device. This is called a static IP address. This means that both 192.168.0.2 and 192.168.0.3 can be assigned automatically or manually, depending on the network and its devices and users. How to Access a 192.168.0.2 or 192.168.0.3 Router All routers are accessible from a web interface, usually called the administrative console, that provides a way to customize the router settings to configure wireless access, change DNS servers, and configure DHCP. If your router has an IP of 192.168.0.2 or 192.168.0.3, enter one of these into the URL address bar of a web browser: http://192.168.0.2http://192.168.0.3 When asked for a password, enter the password the router is configured to use. If you never changed the password, then enter the default password that the router was shipped with. NETGEAR, D-Link, Linksys, and Cisco routers all use different default usernames and passwords. When the console opens, view the devices connected to your network and customize the assigned IP addresses, among other things. This process is usually not necessary, and it's best to go with the router's automatic assignment of IP addresses. You may never need to access the router's admin console because most routers guide users through the initial setup using a wizard.
