IP Address for host-only network not in allowed ranges

[Adam-Klein]

Hello,

I've just done a git clone on this repo and with no changes, done a vagrant up. I then get the below error

The IP address configured for the host-only network is not within the
allowed ranges. Please update the address used to be within the allowed
ranges and run the command again.

  Address: 10.8.8.50
  Ranges: 192.168.56.0/21

Valid ranges can be modified in the /etc/vbox/networks.conf file. For
more information including valid format see:
