The hosts(5) file format is far simpler than a DNS zone file or a dnsmasq(8) config file. IP.add.re.ss name [alias ...]. dnsmasq assumes that the presence of a hosts listing for IP.add.re.ss means that you want a PTR for ss.re.add.IP.in-addr.arpa. to have that name. You can't put any specific DNS records in there; it's the job of dnsmasq to translate hosts into DNS. In addition, PTRs are returned for IP addresses subject to DHCP leases. I don't know how multiple hosts listings for the same IP address are handled by dnsmasq, but I'll bet it's in the [very] fine manual. :) -- Offlist mail to this address is discarded unless /dev/rob0 or not-spam is in Subject: header

Right. I like using a dnsmasq.d directory for things like that, where records for a specific purpose are in their own modular file: conf-dir=/etc/dnsmasq.d -- Offlist mail to this address is discarded unless /dev/rob0 or not-spam is in Subject: header
