Default Ip Address For Router

Last updated on May 31st, 2014

In a typical home or small office network, the “Router” (commonly known as: ADSL Modem/Router) is the device that connects the computer(s) with the Internet. In order to accomplish this task, the router has two(2) IP addresses: One Internal IP Address (commonly known as “LAN”, “Local” or “Private IP Address”) that is used to connect your router and your internal network (computers) and one external IP address (commonly known as “PUBLIC IP Addres”) that is used to connect your router (and your PCs) to the external network (Internet).

Router

The IP Address is a numerical label assigned to each connected network device and it identifies the network location of this device. Commonly, all IP Addresses are based on TCP/IP v4 Protocol and in this protocol every IP Address is constituted by four (4) numbers separated by periods. Typical home and small office (internal) networks has IP Addresses based on this form: 192.168.1.x or 192.168.2.x. In these cases, the router’s internal IP address is 192.168.1.1 or 192.168.2.1, respectively.

Default

In this example, the default gateway uses the IP address 192.168.4.1, which is resolved into a MAC address with ARP in the usual way. The destination IP address remains 192.168.12.3, but the next-hop MAC address is that of the gateway, rather than of the ultimate destination. If you want to the public IP address of your Netgear router, all you have to do is follow these simple steps: Type “192.168.1.1” or “192.168.0.1” into the address bar of your browser. Enter your username and password. Under the Maintenance section, click Router Status. Locate your model’s username and password through searching our table below. Open your web browser of choice. Enter your router’s default IP address. Type in the username and password that you located through our list below. You can follow the steps below to confirm if your computer does get the IP address from the router. Click the network icon and enter the Internet settings page. Click Wi-Fi and choose the connected WiFi SSID. Scroll down the page to the bottom to see the obtained IP address. How to get the (Utility / Firmware)?

Many routers have a Web-based interface in order to be managed and configured. This Web-based interface can be accessed from any computer, by using a common Internet browser (e.g. Internet Explorer, Chrome, Mozilla). So, if you want to access your router’s Web based Interface you need to know the following:

  1. The router’s Administrative credentials, commonly know as Username (or User ID) and Password. To find this information view the router’s manual (manufacturer documentation) or look under your router device at the manufacturer's sticker.
  2. Your Router’s Internal (LAN) IP Address. This information can be found from the router’s manual or from any computer that is connected to the router. To find your router’s LAN IP address from any connected computer, follow the instructions below:

How to find the local (Internal, LAN) IP Address of your Router.

In order to find your router’s LAN IP Address, follow the steps below:

Step 1. Connect your PC with the Router.

Before you continue, make sure that your ‘re physically connected (using a LAN cable or Wireless) with the router (Network). To ensure that:

  • If your router is already configured for Internet access, make sure that you can connect (access) to the Internet.
  • If you want to setup (configure) your router for the first time, then use an Ethernet (LAN) cable to connect your computer’s LAN port with an empty LAN port on the router’s side.

Step 2: Find your Router’s IP local Address (LAN)

In order to find your router’s LAN IP Address from your Windows PC:

1. Press “Windows” + “R” keys to load the Run dialog box.

2. Type “ncpa.cpl and press Enter.

3. At Network Connections, double-click at:

  • Local Area Connection” (if your PC is connected with the network (Internet) through an Ethernet (LAN) cable
  • Wireless Connection” (if your PC is connected with the network (Internet) through a Wireless Card.

4. At Local Area Connection Status window:

Windows 8, 7 or Vista: click “Details”.

Windows XP: Click the “Support” tab.

5. At “Network Connection Details” notice the “IPv4 Default Gateway” value. This value is your router’s IP address.

  • (e.g. “192.168.1.1” in the screenshot below).

Windows XP: Notice the “Default Gateway” value (e.g. “192.168.2.1” in the screen shot below).

How to access your router’s Web interface.

  • To access your router’s configuration interface, open your web browser and at the URL address box, type the “Gateway Value” found in the previous step (e.g. “192.168.1.1”) and press “Enter”. *

* Note: Some router models don’t allow to be managed through Wireless connections. In such cases, try to use an Ethernet cable to manage your router.

  • Type your router’s (Administrator) User name and Password & press “OK” to start managing your router.*

A default gateway is the node in a computer network using the internet protocol suite that serves as the forwarding host (router) to other networks when no other route specification matches the destination IP address of a packet.[1][2]

Role[edit]

A gateway is a network node that serves as an access point to another network, often involving not only a change of addressing, but also a different networking technology. More narrowly defined, a router merely forwards packets between networks with different network prefixes. The networking software stack of each computer contains a routing table that specifies which interface is used for transmission and which router on the network is responsible for forwarding to a specific set of addresses. If none of these forwarding rules is appropriate for a given destination address, the default gateway is chosen as the router of last resort. The default gateway can be specified by the route command to configure the node's routing table and default route.

In a home or small office environment, the default gateway is a device, such as a DSL router or cable router, that connects the local network to the Internet. It serves as the default gateway for all network devices.

Enterprise network systems may require many internal network segments. A device wishing to communicate with a host on the public Internet, for example, forwards the packet to the default gateway for its network segment. This router also has a default route configured to a device on an adjacent network, one hop closer to the public network.

Examples[edit]

Single router[edit]

The following example shows IP addresses that might be used with an office network that consists of six hosts plus a router. The six hosts addresses are:

  • 192.168.4.3
  • 192.168.4.4
  • 192.168.4.5
  • 192.168.4.6
  • 192.168.4.7
  • 192.168.4.8

The router's inside address is:

  • 192.168.4.1

The network has a subnet mask of:

List Of Router Ip Addresses

  • 255.255.255.0 (/24 in CIDR notation)

The address range assignable to hosts is from 192.168.4.1 to 192.168.4.254. TCP/IP defines the addresses 192.168.4.0 and 192.168.4.255 for special functions.

The office's hosts send packets to addresses within this range directly, by resolving the destination IP address into a MAC address with the Address Resolution Protocol (ARP) sequence and then encapsulates the IP packet into a MAC frame addressed to the destination host.

A packet addressed outside of this range, for this example, addressed to 192.168.12.3, cannot travel directly to the destination. Instead it must be sent to the default gateway for further routing to their ultimate destination. In this example, the default gateway uses the IP address 192.168.4.1, which is resolved into a MAC address with ARP in the usual way. The destination IP address remains 192.168.12.3, but the next-hop MAC address is that of the gateway, rather than of the ultimate destination.

Multi-router[edit]

In another example, a network with three routers and three hosts is connected to the Internet through Router1. The hosts' addresses are:

Topological layout of described network
  • PC1 10.1.1.100, default gateway 10.1.1.1
  • PC2 172.16.1.100, default gateway 172.16.1.1
  • PC3 192.168.1.100, default gateway 192.168.1.96

Router1:

  • Interface 1 5.5.5.2 (public IP)
  • Interface 2 10.1.1.1

Router2:

  • Interface 1 10.1.1.2
  • Interface 2 172.16.1.1

Router3:

Cisco
  • Interface 1 10.1.1.3
  • Interface 2 192.168.1.96

Network mask in all networks: 255.255.255.0 (/24 in CIDR notation). If the routers do not use a routing protocol to discover which network each router is connected to, then the routing table of each router must be set up.

Router2 manages its attached networks and default gateway; router 3 does the same; router 1 manages all routes within the internal networks.

Accessing internal resources
If PC2 (172.16.1.100) needs to access PC3 (192.168.1.100), since PC2 has no route to 192.168.1.100 it will send packets for PC3 to its default gateway (router2). Router2 also has no route to PC3, and it will forward the packets to its default gateway (router1). Router1 has a route for this network (192.168.1.0/24) so router1 will forward the packets to router3, which will deliver the packets to PC3; reply packets will follow the same route to PC2.
Accessing external resources
If any of the computers try to access a webpage on the Internet, like https://en.wikipedia.org/, the destination will first be resolved to an IP address by using DNS-resolving. The IP-address could be 91.198.174.2. In this example, none of the internal routers know the route to that host, so they will forward the packet through router1's gateway or default route.[3] Every router on the packet's way to the destination will check whether the packet's destination IP-address matches any known network routes. If a router finds a match, it will forward the packet through that route; if not, it will send the packet to its own default gateway. Each router encountered on the way will store the packet ID and where it came from so that it can pass the response packet back to the sender. The packet contains source and destination, not all router hops. At last the packet will arrive back to router1, which will check for matching packet ID and route it accordingly through router2 or router3 or directly to PC1 (which was connected in the same network segment as router1).
The packet doesn't return
If router1 routing table does not have any route to 192.168.1.0/24, and PC3 tries to access a resource outside its own network, then the outgoing routing will work until the reply is fed back to router1. Since the route is unknown to router1, it will go to router1's default gateway, and never reach router3. In the logs of the resource they will trace the request, but the requestor will never get any information. The packet will die because the TTL-value decreased to less than 1 when it was traveling through the routers, or the router will see that it has a private IP and discard it. This could be discovered by using the Microsoft Windows utility PathPing or MTR on Unix-like operating systems, since the ping will stop at the router which has no route or a wrong route. (Note that some routers will not reply to pinging.)

Utilities[edit]

Various utility software can show the default gateway. On Windows, ipconfig may be used,[4] while on Unix systems, ifconfig or netstat may be used.[5] On Linux netstat has been superseded by iproute2.[6][7]
