[Dnsmasq-discuss] subdomains and dhcp

[Simon Kelley]

You can do what you want, but there are limitations. You'll need to
split your test, stag and prod hosts 1into different IP address ranges.
This will probably mean giving them fixed addresses.

Then declare the various domains and the subnets associated with them,
for example.

domain=test.domain.net,92.168.0.1,192.168.0.10
domain=stag.domain.net,192.168.0.11,192.168.0.20
domain=prod.domain.net,192.168.0.21,192.168.0.30

Finally, you'll need to the config option

dhcp-fqdn

Reading the man page sections for domain and dhcp-fqdn should help make
this clearer.


Cheers,

Simon.
