Error during creating DHCP server inside intnet network [Linux] [v.6.0.14]

I want to add specific network to my VM on NIC attached to Internal Network (intnet). I found CLI command that create this dhcp server with network, mask and scope, but after this I received error.

# VBoxManage dhcpserver add --netname intnet --ip 172.16.2.0 --netmask 255.255.255.0 --lowerip 172.16.2.10 --upperip 172.16.2.254 --enable
VBoxManage: error: Invalid server address
VBoxManage: error: Details: code NS_ERROR_INVALID_ARG (0x80070057), component VirtualBoxWrap, interface IVirtualBox, callee nsISupports
VBoxManage: error: Context: "SetConfiguration ( Bstr(pIp).mutableRaw(), Bstr(pNetmask).mutableRaw(), Bstr(pLowerIp).mutableRaw(), Bstr(pUpperIp).mutableRaw())" at line 428 of file VBoxManageDHCPServer.cpp
VBoxManage: error: Failed to set configuration

If I list dhcp servers I see enabled only dhcp from Host-only adapter.

# VBoxManage list dhcpservers

My network configuration on host:

I don't know what is interface 4. Any ideas? Is there a kind of a conflict between any of these networks? I tried add with different network and scope but always the output was the same.
