Default IP Address for Routers and Modems

Most of the router and modem manufacturing companies set two kinds of IP addresses for their modem and router. These IP addresses are of two types. is one those. One is the “Public IP address” and the second one is “Private IP address”. These IP addresses are chosen based on their area network. The public IP address is for WAN (wide area network) and private IP address is for LAN (local area network). Let’s talk about private IP address.Every router and a modem have a default IP address and each of this IP address is based on the company or the ISP (internet Service Provider) of router and modem.

There are several brands of routers in the market. But all of those use a ip address for their settings. Admin Login is one of them while some use 192.168.o.1.1 you can check that too.

Most of the Routers revolve around this IP address  :-
2) 192.168.o.1
3) 192.168.0.l
We shall now see the major differences among this IP address. IP address

The IP address is a private IP address is a home broadband private IP address. The router companies like D-Link and Netgear provide this address. IP address can be changed using the network router’s management console. generally is a private IPv4 network address used by a home router and modem to form a gateway accessing a management console, pointing to the URL through the Web browser. The problem is that this on a local computer can be accessed by only one device. Each of this address has an username and password provided by the modem and router manufacturers.

192.168.o.1 IP address

Now, you would like to know the difference between this 192.168.o.1 and IP address. But, you will be extremely shocked after seeing what is coming up next now. The IP address 192.168.o.1 actually does not exist at all. Yes, you heard it right, it never actually existed, but still, 192.168.o.1 can be searched in the browser but we never find such IP address. The problem is with the user here, he generally makes a mistake and cannot recognize the digit ‘0’ with the letter ‘o’. IP address follows some standards like private area and each IP address is built according to that standard only.

192.168.0.l IP address

IP address 192.168.0.l may seem similar to the IP address but yet again this address 192.168.0.l is not valid. Yet again, the user makes a mistake in recognizing the digit ‘1’ with the letter ‘I’ in capitals and with the letter ‘L’ in small. when we search http://192.168.0.I in the web browser, we don’t get any result and instead we get a DNS error message in the web browser.

The IP address has some standard rules that have to be followed and these rules are the basic blocks for building a perfect IP address. IP address also has fewer classes
1) Class A
2) Class B
3) Class C
4) Class D
5) Class E

Class A IP address range from to and Supports 16 million hosts on each of 127 networks. Some ranges from also.
The Class B IP address range from to and Supports 65,000 hosts on each of 16,000 networks.
Whereas Class C IP address range from to and Supports 254 hosts on each of 2 million networks.
And Class D IP address range from to which is Reserved for multicast groups.
Class E IP address range from to which reserves for future use, or Research and Development Purposes.

When you will open this ip in your browser you will be easily able to configure the router. You must make the network changes referring to a particular class listed above.
