This is my default gateway

enter image description here

I am trying to set up Static IP for windows server 2016 in Virtual box,Author of this tutorial says..his default gateway is 192.168.1.1..Upon some research,it lead me to believe all default gateways can be either 192.168.0.1 or 192.168.1.1

But mine is not the same..Only issue i can think of is my network card is damaged,so i can't use WIFI any more unless i am hardwired..

So my ask is

1.What might be the reason for my default gateway starting with 13.* and is this my default gateway..

context for the ask:
This default gateway is needed for me to assign a static ip for a windows server 2016 host on a virtual box

Upon some research,it lead me to believe all default gateways can be either 192.168.0.1 or 192.168.1.1

No. That's just the most popular setup in home routers.

The prefix

Traditionally, home networks use the first /24 network out of the "private" 192.168.0.0/16 address range. (Or as it used to be called several decades ago, the first class-C network.) Depending on how you count, "first" is either 192.168.0.0/24 or 192.168.1.0/24.

But it doesn't have to be. If you wanted, you could use any address range for your LAN – not necessarily within the 192.168./16 range, not necessarily within any private range, and not necessarily the size of /24.

In particular, the 10.0.0.0/8 range (10.x.x.x) is also reserved for private use, and is a very common choice when setting up a large network consisting of several dozen subnets.

(Using a public range is also normal – as long as that range actually belongs to you.)

So your computer currently happens to be connected to the 10.137.0.0/16 subnet.

The suffix

There is absolutely no restriction as to what IP address can be used as a gateway, as long as it actually belongs to a routing-capable device on the same link (and normally on the same subnet) as you.

But by convention, the first – or last – address within a network is chosen for the gateway, simply because it's more tidy that way. So you commonly see 192.168.0.1 or 192.168.1.254 as gateways.

And since you are on a 10.137.0.0/16 network, it is reasonable that its first address, 10.137.0.1, will be used for the gateway.

(The last address would be 10.137.255.254, in case you're wondering.)

  • Thank you this was very clear There is absolutely no restriction as to what IP address can be used as a gateway, as long as it actually belongs to a routing-capable device on the same link (and normally on the same subnet) as you.

It looks like dhcp is NOT enabled on your virtual adapter.

  1. Take a known good laptop or computer, plug it into your VLAN in question if applicable. Just lan port if no vlans.

  2. try to get an autoconfig ip. Check the default gateway ip. Then try to ping it.

You can try to ping 127.0.0.1 from the virtual machine to make sure the tcp/ip stack is working properly.

Your default gateway should always be in the same network subnet as your server/pc. If the nic is on "192.168.56.x" your default gateway(router) should be something like 192.168.56.1

Post back with more info on your setup and I can help you further.

  • Thanks,i believe tcpip stack is working properly,reason being,if I change obtain ip address automatically internet on virtual machine works

  • "If the nic is on "192.168.56.x" your default gateway(router) should be something like 192.168.56.1" – yes, that's true for the virtual machines, but the ifconfig output is from the host. It's normal that the virtual adapter on the host will be statically configured, since the host itself is the gateway for those VMs.
