Change scale set virtual network default address 10.0.0.0/16

Question

By default, when creating a scale set through the Azure Portal, that scale set has a a virtual Network with the default address 10.0.0.0/16, even if you are already using that Network for other instances.

1) Does anyone knows how i can change that network range for example into 192.168.0.0/16 and make sure that my instances that now have an ip address from the range 10.0.0.0/21 will receive an IP address from 192.168.0.0/16. I tried to delete the 10.0.0.0 subnet and the Network with the instances deallocated but i was not allowed (failed message)

2) Or is it possible to create a new scale set through the portal and choose what virtual network address range he wants? Thanks

Answer 1

Does anyone knows how i can change that network range

We can't modify virtual network addressPrefix after it created.

Or is it possible to create a new scale set through the portal and choose what virtual network address range he wants?

We can use Azure VMSS template to deploy VMSS, in this way, we can modify the addressPrefix and subnetprefix before we create VMSS.

First we can use google to search a VMSS template, for example:

And select Edit:

Then we use the template to deploy VMSS, here is my result:
