How to avoid hostname leaks when using MAC randomization in debian-9

[Brotherfill]

Hi,

To avoid hostname leaks I add # at the beginning of line 'send host-name=gethostname' in /etc/dhcp/dhclient.conf

Do you suggest to use this method or to set a static ip?

AFAIK the hostname should always be sys-net, and you are
fingerprintable as a qubes user anyway, so I don't think the hostname
is in any way interesting unless you have a uniquely named (read:
non-default) NetVM.
