Setting IP address and hostname of a Vagrant box

mkdir -p testsrv
cd testsrv
vagrant init generic/freebsd13

A new `Vagrantfile` will be created and the following message will be displayed:

A `Vagrantfile` has been placed in this directory. You are now
ready to `vagrant up` your first virtual environment! Please read
the comments in the Vagrantfile as well as documentation on
`vagrantup.com` for more information on using Vagrant.

In the Vagrantfile, the following line is commented out:

# config.vm.network "private_network", ip: "192.168.33.10"

We replace this line with the following two lines, which set the IP address to `192.168.121.101` and the hostname to `testsrv.example.com`.

config.vm.network "private_network", ip: "192.168.121.101"
config.vm.hostname = "testsrv.example.com"

In the host machine on which the Vagrant box is running, we need to add an entry to the `/etc/hosts` file so that we can refer to the Vagrant box by its hostname instead of its IP address.

echo '192.168.121.101 testsrv testsrv.example.com' | sudo tee -a /etc/hosts

The following output should be displayed:

192.168.121.101 testsrv testsrv.example.com

vagrant up

A successful boot will result in output similar to the following:
