Unable to create subnets

Anonymous

As a part of Azure LAB (https://gsi.learnondemand.net/Class/572405) I was attempting to create virtual networking (Lab 8). As per exercise, I could able to create 1st subnet (10.40.0.0/24). But when I tried to create another subnet (10.40.1.0/24) i kept getting error as "The subnet IP range is not contained in this virtual network's address space"

Similar issue I faced when I was attempting "Implement Monitoring"

In this Lab, In task 4 – its mentioned to review the default monitoring setting on AZ VM. Means its expected VM is already created & We need to review the settings. But I didn’t found any existing VM available also LAB is not allowing me to create a new VM.

I followed the interactive Lab for these modules & ensured I am not doing anything wrong. Please look into this.

Welcome to the Microsoft Q&A Platform. Thank you for reaching out & I hope you are doing well.

I am not able to check the Lab module as it requires user authentication.

As mentioned by Sreeju Nair , your subnet's address space must be an available range in the VNET's address space.

Only then you shall be able to create a subnet inside that VNET.

For more details, please refer : Add a subnet

Please let us know if we can be of any further assistance here.

Thanks,

You need to check your VNet address range. If your VNet also has address range, 10.40.0.0/24 then you can not create a subnet in that VNet with address range 10.40.1.0/24, as it is outside the VNet address range.

See the subnet address range requirements from the following URL.

Hope this helps
