Admin router IP address is a private IP address, default for some types of broadband routers in the home. It is also often assigned to individual devices in a home network when a router has an IP address of As a private IP address, does not have to be unique across the entire Internet, but must be unique in the local area network.

Although this IP address is set by default for some routers, any router or computer on the local network can be set to use

How Private IP Addresses Work

No special meaning or value for individual IP addresses – they are simply designated “private” by the Internet Assigned Numbers Authority (IANA), a global organization that manages IP addresses. Private IP addresses are only used on private networks and can not be accessed from the internet, but can only be accessed from devices on private networks. This is why modem and router can easily operate by using the same private IP address. To access the router from the Internet, you must use the public IP address of the router.

The address range reserved by IANA for use on private networks is in the range of 10.0.x.x, 172.16.x.x, and 192.168.x.x.

Use to connect to a router

If the router is using on the local network, you can log into the administration console by entering its IP address in the URL address bar of the web browser:

The router then prompts for the username and password for the administrator. All routers are configured with the manufacturer’s default username and password. The most common default username is “Admin“, “1234” or no username. Similarly, the most common passwords are “admin“, “1234” or nothing, the same as the username. The default username/password is usually written on the back of the router.

It’s not usually necessary to access the router’s administration interface, but it can be useful if you’re having trouble connecting.

Why did become popular?

Manufacturers of routers and access points must use IP addresses in a private area. Initially, broadband router manufacturers such as Linksys and Netgear chose the default of 192.168.1.x. Although this technical range starts at, most people would think that a sequence of numbers would start with 1 instead of zero, so would be the best choice for the beginning of a family network address range.

With this router assigned the first address, it assigns the address to each device on the network. Therefore, IP becomes the most common starting point.

Networked devices do not achieve better performance or better security from IP addresses, whether it is, or any other private address.

Assigns to a device

Most networks assign private IP addresses automatically using DHCP. This means that the device’s IP address can be changed or reassigned to another device. Trying to assign this address manually (a process known as “fixed” or “static” address assignment) may also be performed, but may cause a connection failure if the network router is not configured. corresponding configuration.

Here’s how it works:

  • Each local router using DHCP is configured with a series of addresses that it can allocate to clients.
  • On the home router whose default address is, the default address for the guest address is to Most routers will assign IP addresses to network devices starting at the beginning of this range, so you rarely see IP addresses on your network outside of the scope.
  • A router generally will not check that (or any other address in this range) has been assigned to a client manually before automatically assigning it to a client. This can cause IP address conflicts where two devices on the same local network try to use the same IP address.
  • IP address conflicts will disrupt the network interface of both devices. For these reasons, you should allow your router to control the assignment of IP addresses in the home network.
