What is the difference between gateway and default gateway




















Fortunately, the default gateway address is pretty easy to find. If your operating system of choice is Windows, simply head to the Control Panel and select the Network and Sharing Center. Depending on the version, click the Change adapter options or Change adapter settings. Next, locate the network you would like to find the default gateway for.

When you spot it, double-click on it and choose "Details" from the pop up. There, you'll be able to read the IPv4 Default Gateway which will be somewhere on the list. The process is even simpler for MacOS users: go to System Preferences and select Network, followed by the name of the network you're using.

If you're feeling more adventurous, you can also try finding the default gateway with the help of the command line utility.

It's worth mentioning that this method is probably best left to more experienced tech users, but if you're adamant about giving it a go, then open the Command Prompt for Windows, or Terminal on Linux and macOS.

With Windows, the next step is to type in the command 'ipconfig' command. If you're using a Mac device, type in 'netstat -nr grep default'. For Linux, this will be 'ip route grep default', followed by return. RedGrittyBrick is absolutely correct with his answer "a router and a gateway are essentially the same" , some other responders are confusing the terms or, to put it kindly, have misunderstood the question or wikipedia. As far as routing goes the term "gateway" is almost only ever used in conjunction with "default", and that "gateway" provides a route to every network for which there is no more specific route available.

By definition then, the gateway must be a device that does routing, it could be a dedicated device, specifically a router, or a host which has been configured to route, but it is doing the same job. Thus a gateway can be a router and a router can be known as a gateway.

In answer to your question about getting out to somewhere that is not on the local subnet, RedGrittyBrick is again correct about the ICMP redirects, in addition, the process that a host goes through when sending out a packet is this:. Thus it can be seen that every host makes a routing choice of its own prior to sending out packets of course this data is cached so lookups are not occurring for every single packet. A router serves as a gateway, but with additional functionality.

Per wikipedia: "A gateway is an essential feature of most routers, although other devices such as any PC or server can function as a gateway. Packets from another source passing through a router will have it's TTL reduced by 1 at each hop. If the packets enter the router with a TTL of 1 and the router is the destination then the traffic will be received by the router. If the router is not the destination the packets will have their TTL reduced to 0 before exiting the router and will be dropped.

In your case, the gateway knows the router and forwards all requests which are for non-internal addresses to the router. Usually the "gateway" is a machine that make NAT "masquerading" and that means that the gateway send out the request for data in the name of private IPs for which the respective machine is gateway, and when the data is back, pass the data to those private IPs.

If you will, it can be said that the gateway "impersonates" the private IP machines with regard to the internet. A router OTOH just rutes packets from one interface to the other. Having a set of rules static set up or dynamically set up routing protocols the router know to send the packets on a specific interface in order for those packets to reach the desired network. Now if the address of the gateway ip address not the mac is something like Now the gateway is further connected to internet which has a huge huge network of gateways but this time those will be called as routers.

So in your case the first hop is from your house to the gateway that is from Hope you get it. Sign up to join this community. The best answers are voted up and rise to the top.
