- TCP/IP computer networks use both the IP addresses and MAC addresses of connected client devices. While the IP address changes over time, the MAC address of a network adapter always stays the same. There are several reasons you might want to know the MAC address of a remote computer, and it's easy to do by using a command line utility such as.
- Changing your IP address can be useful if you want to avoid being attacked by other users who are targeting your IP address, or if you simply want a new online identity from an IP standpoint. You can change your IP address on a Mac at any time through System Preferences.
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:
- 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:
- 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.
Router1
Network ID | Network mask | Gateway | Interface (examples; may vary) | Cost (decreases the TTL) |
---|---|---|---|---|
0.0.0.0 (default route) | 0.0.0.0 | Assigned by ISP (e.g., 5.5.5.1) | eth0 (Ethernet 1st adapter) | 10 |
10.1.1.0 | 255.255.255.0 | 10.1.1.1 | eth1 (Ethernet 2nd adapter) | 10 |
172.16.1.0 | 255.255.255.0 | 10.1.1.2 | eth1 (Ethernet 2nd adapter) | 10 |
192.168.1.0 | 255.255.255.0 | 10.1.1.3 | eth1 (Ethernet 2nd adapter) | 10 |
Router2
Network ID | Network mask | Gateway | Interface (examples; may vary) | Cost (decreases the TTL) |
---|---|---|---|---|
0.0.0.0 (default route) | 0.0.0.0 | 10.1.1.1 | eth0 (Ethernet 1st adapter) | 10 |
172.16.1.0 | 255.255.255.0 | 172.16.1.1 | eth1 (Ethernet 2nd adapter) | 10 |
Router3
Network ID | Network mask | Gateway | Interface (examples; may vary) | Cost (decreases the TTL) |
---|---|---|---|---|
0.0.0.0 (default route) | 0.0.0.0 | 10.1.1.1 | eth0 (Ethernet 1st adapter) | 10 |
192.168.1.0 | 255.255.255.0 | 192.168.1.96 | eth1 (Ethernet 2nd adapter) | 10 |
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 http://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, netstat
may be used.[5] On Linux netstat
has been superseded by iproute2

What is the Default Gateway?
A Default Gateway is used as an access point or IP router that allows a computer in a network communicates information with another computer in another network or the Internet.
Better still, you can liken default gateway to your main gate or door to your house. Assume you are inside your house, you will have to first pass through the main gate or your door, open it and then lead yourself at your destination. Also, assume that you are returning from school or work, you will have to pass through that same door or gate to enter your house. That gate or door is assumed to be your default gateway.
Without the default gateway, the network is separated from the outside. For instance, your computer might request for an online web page, your default gateway first process the request before it leaves the local network to reach the internet.
It is very important to know the IP address of the default gateway, that is, your router on your home or enterprise network if you want to effectively troubleshoot a network fault or manage the activities of the router.

On most home or enterprise networks, where there are only one router and different inter-connected devices, the private IP address given to your router is usually the default gateway IP address. This IP address is the one that your router uses to communicate with your local network and which all devices send traffic to by default.
This IP address is called 'Default gateway' on Windows PC while it is called .router' on macOS and Linux operating systems. Google books for mac. On other operating systems, it is called either 'gateway' or 'gateway route'.
Functions of Default Gateway
· It serves as an access point to other networks.
· Connects the local network to the internet.
· It is used for management purposes .

How fast can you know your Default Gateway IP Address?
Knowing your default gateway IP address is very essential. The question is, 'how fast can you know it?' Well, you shouldn't spend much time on finding your default gateway IP address in Windows, Mac OS X and Linux. However, if you are using Windows OS, you should be able to locate it in lesser minutes using ipconfig procedure , which will be discussed later.
Download bittorrent for windows 10. You just have to press few clicks to locate the default gateway IP address which is saved in Windows' network settings. You should note that you will be able to locate the default gateway of your computer on Windows 10, Mac OS X, and Linux as described below.
Best Ways to Find Default Gateway IP Address on Windows 10
To find your default gateway IP address on Windows 10, there are two ways of locating it. The first method is the through the 'Graphic Interface' and you will prefer using the ipconfig method if you have experience using commands in Windows. You must be informed that the instructions that will be provided below will only help you find the default IP address on wired and wireless home and enterprise networks. However, you may have more than one gateway or more complex routing with wider networks which have more than one single router.
Let's get started with the first method.
Method 1 : Using the ' Graphic Interface '
Step 1: You open the Control Panel , which is just among the desktop's icons. You can, either way, open the Control Panel through the Start Menu. (You make the process shorter by going straight to Network Connections link which is on Power User Menu , which you can access via the WIN=X keyboard shortcut. You jump to step 4 if you end up reaching that route.)
Step 2: After opening the Control Panel, click on Network and Internet. You may not be able to view this link if Control Panel icons view by Large icons or Small icons but you can view by only viewing by the Category option. If peradventure you are viewing with Large and Small icons, you can click Network and Sharing Center and jump to Step 4.
Step 3: You are now on the Network and Internet window. Then click Network and Sharing Center which is the first link you will see.
Step 4: Open the Network Connections screen. Click Change Adapter options just right in the middle of the window. If you reached this step-through Control Panel, click on the Change adapter settings from the left panel. If it says change or manages, no qualms, changes will not be made to the network settings on the Windows. What you are doing is just viewing the already setup default gateway and not making changes.
Step 5: Look for the network connection whose default gateway you want to view. You will notice that your wired network connection is indicated as either Ethernet or Local Area Connection and your wireless connection indicated as Wi-Fi or Wireless Network Connection.
Step 6: You can then double-click on the network connection link. Immediately, an Ethernet Status, Local Area Connection Status or Wi-Fi dialog box is opened varying on the name of the network connection you are opening. However, if you get something like Devices, Printers or Properties, it is telling you that the network connection you opted for does not have a status to show you. What you do next is go back to Step 5 and look for another connection different from the one you just picked.
Step 7: Click on Details option.
Step 8: Find IPv4 Default Gateway, IPv6 Default Gateway, or Default Gateway under the Property column, based on the kind of network you are using.
Step 9: Find the IP address indicated as the Value for that property. Great! You have now gotten the Default Gateway IP Address your Windows is using right now. It is very much advisable to document your default gateway IP address to avoid unnecessary repetition of these steps.
Step 10: On knowing your default gateway IP address, you can use it for the purposes you intend to use it for like accessing your router or troubleshooting a connection problem.
Method 2: Using the ' IPCONFIG '
To quickly locate your default gateway IP address, the ipconfig command method will help you.
Step 1: Open Command Prompt.
You can open Command Prompt by first selecting the Start button , then, type ' cmd '. Then click Command Prompt from the list.
You can also open the Command Prompt by selecting the Start button. Then, find the Windows System folder from the apps listed and tap. You will then see the Command Prompt under the Windows System folder.
You can open the Command Prompt if you are using a keyboard or a mouse. Press WIN+X with your keyboard or right-click the Start button with your mouse, then you click Command Prompt from the menu that displays after this step.
Step 2: On the Command Prompt window, you type ipconfig and press the Enter key.
Step 3: You will locate your default gateway IP address next to Default Gateway.
Perhaps, you want to make the information provided less complex, you can type ipconfig | findstr 'Default Gateway' . This automatically makes the information shortened and you can easily see through your default gateway IP address. This method can be only employed if you are using only one active connection.
