How to find your RPNv1 gateway

Reviewed on 30 October 2023 • Published on 10 November 2021

Your RPNv1 gateway may differ from one Dedibox to another for technical reasons. It is normally pushed by DHCP, and configured automatically. However, in some cases you may need to know the details of the gateway.

You can find the RPNv1 gateway for your Dedibox in the Scaleway console, or by running the following commands.

Before you start

To complete the actions presented below, you must have:

A Dedibox account logged into the console
A Dedibox dedicated server with an RPN interface

Connect to your Dedibox using SSH.

Install the iproute2 package, if not done yet. For Debian and Ubuntu, use the following command to install it:

apt install iproute2

Run the ip route show command to display your RPNv1 gateway. An output as the following displays:
```
# ip route show
10.90.0.0/XX via X.X.X.X ...
```
The output contains the following information:
- 10.90.0.0/XX: Your RPNv1 IP subnet. The part after the / represents the CIDR netmask of your subnet.
- X.X.X.X: The IP address of the gateway. The gateway is always the first IP of the subnet.
Note
The gateway does not ping, this is normal behavior.

Tip

If you know your RPN netmask, you can also find your gateway by using ipcalc.

Run the following command to calculate the IP address of your RPNv1 gateway:

# ipcalc -b [SET_HERE_YOUR_RPN_IP]/[CIDR_NETMASK] | grep HostMin
HostMin: X.X.X.X

The gateway is located at the IP address in place of X.X.X.X.
