—IP Address for Local Networks

The third IP address in a range often used by home computer networks

A router can assign to any device on its local network automatically, or an administrator can do it manually.

Automatic Assignment of

Computers and other devices that support DHCP can receive their IP address automatically from a router.

The router decides which address to assign from the range it is set up to manage. When the router is set up with a network range between and, it takes one address for itself – usually – and maintains the rest in a pool. Normally the router assigns these pooled addresses in sequential order, starting with and then next and so on, although the order is not guaranteed.

Manual Assignment of

Computers, game consoles, phones, and most other modern network devices allow setting an IP address manually. The text or the four digits 192, 168, 1 and 3 must be keyed into a network setting configuration screen on the device. However, simply entering your ​IP number does not guarantee the device can use it. The local network router must also be configured to include in its address range.

Issues With

Most networks assign private IP addresses dynamically using DHCP.

Attempting to assign to a device manually, which is a process called "fixed" or "static" address assignment, is also possible but not recommended on home networks due to the risk of IP address conflict. Many home network routers have in their DHCP pool by default, and they do not check whether it has already been assigned to a client manually before assigning it to a client automatically.

In the worst case, two different devices on the network are assigned – one manually and the other automatically – resulting in failed connection issues for both devices.

A device with IP address dynamically assigned may be reassigned a different address if it is kept disconnected from the local network for a long enough time period.  The length of time, called a lease period in DHCP, varies depending on the network configuration but is often two or three days. Even after the DHCP lease expires, a device is likely to still receive the same address the next time it joins the network unless other devices have also had their leases expire.
