IP Address Assignment for VNet

We are currently on-premise, using IP addresses in the 100.1.x.x range, and plan to migrate some of our environment to Azure.
When building a system in Azure, is it possible to assign IP addresses within this range?

I have checked the following description, but I thought there might be a possibility that it might not be available in the future, etc.,
so I asked the question.

It is recommended to use the address ranges enumerated in RFC 1918.
These ranges are reserved by the IETF for private, non-routable address space.

    @ATSUKO YONEDA ,

    You can use any IP space for Azure Virtual Network. It is not necessary that you need to stick with RFC 1918. As long as there is no overlap of IP address between On-Premises and Azure, you can connect to Azure privately without any issues.
