can not allocate ip from dhcp
Description
I setup a foreman server and use it to discovery host, But host cannot allocate ip address from the dhcp on foreman server.
The smart proxy sctive features are TFTP, DHCP, Puppet, Puppet CA, Discovery, Dynflow, and SSH. And the Discovery service show me as following:
*Discovery
Version1.0.4
Data not available for Discovery*
- dhcpd.conf
omapi-port 7911;
default-lease-time 43200;
max-lease-time 86400;
ddns-update-style none;
option domain-name "tower.com";
option domain-name-servers 192.172.30.1;
option ntp-servers none;
allow booting;
allow bootp;
option fqdn.no-client-update on; # set the "O" and "S" flag bits
option fqdn.rcode2 255;
option pxegrub code 150 = text ;
- PXE Handoff.

You need to configure a range on your DHCP server if you want it to allocate IP addresses for unknown hosts. Using the installer, set the dhcp_range parameter to something like "192.172.30.10 192.172.30.50" to have it configure it, or do it yourself.
This doesn't appear to be a bug in Foreman, please prefer the mailing list etc for support queries: https://theforeman.org/support.html

Thanks, it works. The guide https://theforeman.org/plugins/foreman_discovery/6.0/index.html does not contain this issue. Maybe we need to add it.
