How to modify internal dhcp to IPv4 ??
I want to simulate a IPv4 internal environment, but vbox's internal dhcp is IPv6 default ......
And in the VirtualBox Menu, File --> Prefernces --> Network --> ...... Only "Host-only Networks ", no "Internal Networks" ......
Can't modify internal dhcp to IPv4 ???

VB does not provide a direct IPv6 DHCP, unless you specify a range manually, just like IPv4. Your interfaces get a default Link-Local address, that starts with fe80. Check
http://en.wikipedia.org/wiki/IPv6 for more IPv6 info.

No, it's not. IPv6 is only available because you have the proper modules loaded on the systems. If you blacklist the IPv6 module, you don't have IPv6 connectivity. And like I said, check that Wikipedia link. Every NIC gets a Link-Local address. It's perfectly normal and has nothing to do with VB. Sure you can ping6 both systems, because they are connected to each other, in the same way a normal ping4 would work if the NICs have an IPv4 address on them.
Now, what do you not understand about this? VB does NOTHING with the Link-Local addresses, the OS itself does it all.
