What Exactly Is a Default Gateway Address?

You may have seen the expression ‘default gateway’ on Microsoft Windows network configuration screens. Within the area of computer networking, the device which passes the traffic between the local subnet and the other devices on other subnets is called a default gateway. Thereby, a default gateway frequently links a local network with the Internet, even though there are also internal gateways for local networks as well. When using Microsoft Windows, a default gateway’s IP address of a computer can be accessed in the utilities ipconfig or ‘winipcfg’.

How Many Kinds of Internet Default Gateways Are There?

There are usually two kinds of Internet default gateways, which are the following:

1. The home router takes on the role of the default gateway on home and/or small business networks which use a broadband router in the aim of sharing the Internet connection.

2. On the other hand, on home and/or small business networks which do not use a router (for example, homes which use dial-up Internet access) the default gateway is the router at the Internet Service Provider location. However, default network gateways are also configured by by means of a simple PC or computer as a replacement for a router. In fact, these types of gateways employ 2 network adapters. One of these is linked with the local subnet and the other one to the external network.

Nevertheless, either gateway computers or routers can be made use of to be linked with network local subnets (as for example, those used in large businesses).

So What Exactly is the IP Address?

The definition of this IP address is the following: it is a default address for certain kinds of routers for the network, together with some Cisco brand routers. In addition, this default address can be utilized by private networks servers. In fact, these devices are frequently granted entry by way of the path within a Web browser. This address is also often described as a default gateway address, considering that it usually stands for the local section of the connection of a router to the Internet. The IP address is more often located in business networks rather than homes (as these incline to use the routers which have a default address within the 192.168.x.x series. It is necessary to say that both the 10.x.x.x as well as the 192.168.x.x series which happen to be private IP address ranges.

Some More Information About The IP Address.

This IP address is dubbed as a default gateway address, meaning that it is the IP address which is usually used as the default IP address for certain network routers. Normally, this IP address is used by Comcast-branded Wireless Gateway appliances that are used to join wi-fi networking and a standard cable internet modem.


Due to the fact that the IP address happens to be a default gateway address, it is logical that it will not be assigned to appliances on a network as the local IP address. By and large, any device or appliance which is on the network has a variant of the default gateway address which substitute the forth number. An example of this is the following one: it is likely that the very first computer which is linked to this router will be allocated with the number or address Hence, this series of IP addresses which can be assigned have the capability of being changed in the settings of the router.

What Is A Router’s Default Gateway Address Used For?

Usually, the default gateway address of a router is used for accessing the administrative settings page of the router. Then, from this location, the users are able to alter the wireless networking information of the router, the DHCP assigned range of IP, as well as updating firmware, setting added security modes, as well as other basic and/or advanced settings which is made available by the router’s manufacturer. The only thing the user needs to make sure of is that he or she types in in their favorite internet browser (as for example Internet Explorer of Firefox), and then the router is sure to prompt for the admin’s login. However, this information may vary among diverse routers, and thus it is necessary to check out any available router documentation to find more details.

What About Changing the Default Gateway Address?

There are certain routers which support the capability of altering the default gateway address, although generally speaking, this is not advisable. It is a network specialist who should be making a possible decision about any changes to the router default gateway address, and this should be done only if it is completely necessary.

What Are The Risks?

One of the possible risks is that the router may go back to the previous IP address and produce a loss of the network and internet connections of the devices.

In fact, if it should ever happen that a router needs to be replaced and the new one has another default gateway address, some settings on the computer may need to be altered in the router itself in order that the devices can work in a correct manner. An example of this is: if the computer or some additional device on the network uses “static” or on the other hand, “assigned” addresses, they will also have to be altered so that can correspond with the format of the new router default gateway address.
