How to force docker to run its instance on 192.168.99.100 using Docker Toolbox on Windows 10

I am using Docker Toolbox for Windows and my docker instance was running on VirtualBox
The ip of Docker Machine ‘default’ was 192.168.99.100.

I tried doing different things over last two days. Now when i start my Docker the ‘default’ IP comes out to be 192.168.99.101

I have around 5 containers running + 4 other process running independently. The IP Of 192.168.99.100 is registered in my Application configuration.

Since i am getting new IP 192.168.99.101 when i start docker using Docker Tool Box --> My application is failing.

How can i make docker-machine default to work on previous IP 192.168.99.100?
Any pointers, document will be helpful.
If it is not possible to make this happen please let me know.

I know for sure 192.168.99.100 is free.

Please note i am no expert in docker. I am new to it.
