Hello experts, I am Avinash. I have been trying to set some virtual machines on Oracle Virtual Box.
OS: Win 10 Pro 64 Bit
Virtual Box version: Version 5.2.0 r118431 (Qt5.6.2)
I have been trying to add DHCP configuration to the virtual host-only network adapter, but it ends up in the following error.
Failed to save DHCP server parameter.
Server address within range bounds.
Result Code: E_INVALIDARG (0x80070057)
Component: VirtualBoxWrap
Interface: IVirtualBox {9570b9d5-f1a1-448a-10c5-e12f5285adad}
Callee: IDHCPServer {00c8f974-92c5-44a1-8f3f-702469fdd04b}

The IP addresses I am using are 172.168.190.100/16. -- for DHCP
Range 172.168.190.1 -- 172.168.190.200
Moreover, there's no default Host Only Adapter installed with the Virtual Box and I don't see any option in Preferences --> Network for Host Only Adapters. In the Preferences --> Network I only see the NAT network.

I searched the blogs but couldn't find anything that would solve the issue.
I am not sure if the following data would be of any relevance in solving my query, I am putting it nevertheless.
I had to uninstall the Oracle Virtual Box twice and reinstall it because Virtual Box was only displaying 32-bit options. Some of the forums suggested to reinstall the app. Only when I followed this link Why is VirtualBox only showing 32 bit guest versions on my 64 bit host OS? - fixedByVonnie , I could solve that issue, but then, it started troubling me with the DHCP configuration.
Any help is appreciated. Thank you.
