[Dnsmasq-discuss] keep FQDN for DHCP lookups?

[Bernd Helm]

Im using LXC with a custom config:

dhcp-hostsfile=/etc/lxc/dnsmasq-hosts.conf

and that dnsmasq-hosts.com file contains hosts like:

staging.wip.mydomain.com,192.168.34.11
staging.rog.mydomain.com,192.168.34.21

problem is, that both hosts get the same ip, because dnsmasq reduces the
client's hostname just to "staging".

The log reads "Ignoring domain wip.mydomain.com for DHCP host name staging"

i use FQDN's that are public resolveable to assign local IPS to the vms
(on a bridge interface, i forward traffic using haproxy).

is there a way to tell dnsmasq to NOT remove the domain part when
searching the dhcp-hostsfile and saving leases?

Thank you.
