IP Address for Local Networks is the fifth IP address on the private network whose assignable address range starts at Home networks with Linksys broadband routers most commonly use this private IP address range. A router usually assigns to devices automatically, although an administrator can do it manually instead.

Automatic Assignment of

Computers and other devices that support DHCP usually 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 a router is set up on the network, it takes one address for itself (usually and maintains the rest in a pool. Normally the router will assign these pooled addresses in sequential order, in this example starting with followed by and so on up to and beyond (but the order is not guaranteed).

Manual Assignment of

Computers, game consoles, printers and some other types of devices allow their IP address to be set manually. The text “” or the four numbers – 192, 168, 1 and 5  must be keyed into a configuration screen on the unit. However, simply entering the IP number does not guarantee it is valid for the device to use: 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 (so-called “fixed” or “static” address assignment) is also possible. However, routers using the network will typically have in their DHCP pool by default, and they will not recognize whether it has already been assigned to a client manually before attempting to assign it dynamically.

In the worst case, two different devices on the network will both be assigned the same address (one manually and the other automatically), resulting in an IP address conflict and broken connection issues for both.

A device with IP address dynamically assigned to it may be re-assigned 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 2 or 3 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.
