Different IP Address for Local Networks

19 19 is the fourth IP address in the range between and 19 Local broadband routers often use this limitation when specifying addresses for local devices. The router can automatically assign to any device on the local network or the administrator can manually do it.

Automatic delegation of 19
DHCP and other devices can automatically obtain an IP address from a computer router that supports a dynamic address assignment. The router determines which address to operate (which is referred to as "DHCP Pool").

For example, the router installed with local IP address 19 usually maintains all addresses as and ends in 19.2688.1255 in its DHCP pool. Routers usually specify this pooled address in ascending order (but the order is not confirmed). In this example, the assignment is the third address in row 1 of 2,168.1.4 (19, 2,168.1.2 and 19,218.1.3) for the assignment.

Manual Assignment 19
Computers, phones, game consoles, printers, and some other device types allow you to manually set an IP address. The text "19" or numbers 192, 168, 1, and 4 should appear on the device's IP or Wi-Fi configuration screen. Entering an IP number only does not guarantee that the device can use it. The local network router should also be configured to support its subnet (network mask)

19 Problems with
Most networks assign a private IP address using DHCP. Manually assigning a device to (a process called "fixed" or "static" address assignment) is also possible. If this is not done by trained professionals, then it is not recommended.

Due to IP address conflicts, two devices on the same network receive the same address. Many home network routers are by default in their DHP pool and do not check whether the client is handled manually before the client is assigned automatically. In the worst case, there will be two different devices on the network - Manually and automatically assigned. Both of these connection problems will break

A device that is dynamically assigned IP address can be assigned to a different address if it has long been disconnected from the local network. The length of time, known as the lease time in DHCP, is based on network alignment, but it is often two or three days. Even after the DHCP Lease expires, the device will receive the same address on the network for the next time the lease is finished with other devices.
