20660,hostonly network should allow all valid Private IPv4 ranges by default,jehiah,,"From https://www.virtualbox.org/manual/ch06.html#network_hostonly

  VirtualBox will only allow IP addresses in 192.68.56.0/21 range to be assigned to host-only adapters. For IPv6 only link-local addresses are allowed.

By default VirtualBox should allow IPv4 ranges in all [https://datatracker.ietf.org/doc/html/rfc1918#section-3 RFC 1918 Private IP ranges] including

* `10.0.0.0/8`
* `172.16.0.0/12`
* `192.168.0.0/16`

This restriction (new in 6.1.28) was a breaking change for users using valid private IP addresses outside of `192.68.56.0/21`.
