Why is the router's default gateway typically 192.168.1.1?

Interface

1. Historical level

That is, before broadband spread around the world, the default internal address for both Enterprise and home gateways is 192.168.0.1. There are three reasons, one is that the Gateway Superior has no private address, so from the beginning of 192.168.0 will not have any conflict; second, the user has a basic professional quality, customer service read one ninety two dot one sixty eight dot o dot One doesn't really try to knock a letter O; third, Cisco believes that IPv4 addresses need to be saved, and all addresses should be used from the minimum by default.

Well yes, please do not doubt the second reason and the importance of the third reason. In particular, the third, the former Cisco often propaganda IPv4 will soon run out of the so-called three years after the claim for nearly 20 years.

　2, after the broadband began to become popular, began to gradually have a brand gateway using 192.168.1.1.

The reason continues to be three: one is the popular broadband access in the U. Coaxial cable households actually need to use the community NAT, and the community NAT equipment is the earliest use of commercial gateways, they are the default 192.168.0.1. The same is true of Internet services in many commercial and residential buildings. So have to let end user's equipment with 192.168.1, avoid 0 network segment.

Second, the user's general quality has been lowered, beginning someone to knock the letter o into the browser address bar. Third, the operator customization began to rise, the birth of a group of small factories specifically for some operators to create routers, these manufacturers from the beginning to create a direct built-in router address is 192.168.1.1.

　3, after the popularization of broadband, no one used 192.168.0.1.

The reason is still ... Only two had this time. First, we found that we all use 192.168.1.1, customer service is also convenient, the factory also defaults to the downstream manufacturers do not need to specifically modify. The second is in the broadband development process common virus attempts to destroy the home network, are centralized scanning 192.168.0 network segment, or to the network Segment broadcast packet, this network segment into a high-risk network segment.

At this point, we are not very used 192.168.0.
