Welcome to the OpenBSD/amd64 6.4 installation program.
(I)nstall, (U)pgrade, (A)utoinstall or (S)hell? i
At any prompt except password prompts you can escape to a shell by
typing '!'. Default answers are shown in []'s and are selected by
pressing RETURN. You can exit this program at any time by pressing
Control-C, but this can leave your system in an inconsistent state.
Terminal type? [vt220]
System hostname? (short form, e.g. 'foo')
A response is required.
System hostname? (short form, e.g. 'foo') test
Available network interfaces are: vio0 vlan0.
Which network interface do you wish to configure? (or 'done') [vio0]
IPv4 address for vio0? (or 'dhcp' or 'none') [dhcp]
vio0: bound to 100.64.1.3 from 100.64.1.2 (fe:e1:bb:d1:f6:c9)
IPv6 address for vio0? (or 'autoconf' or 'none') [none]
Available network interfaces are: vio0 vlan0.
Which network interface do you wish to configure? (or 'done') [done]
