As far as I know, there is no technical or security reason why a Dnsmasq-like
server would *need* this limitation, but Dnsmasq has it due to design
limitiations.
Dnsmasq either responds to a request entirely locally (using /etc/hosts,
records from the config file, and records from DHCP) or reli
There are much smarter people than me here, but if I might chime in:
Two basic assumptions in networking are that no two separate devices will
share the same MAC address, and a device's MAC address doesn't change after
it's manufactured. Obviously there are practical exceptions (spoofing, privacy

There's also SIGHUP:
"When it receives a SIGHUP, dnsmasq clears its cache and then re-loads
/etc/hosts and /etc/ethers and any file given by --dhcp-hostsfile,
--dhcp-hostsdir, --dhcp-optsfile, --dhcp-optsdir, --addn-hosts or --hostsdir.
The DHCP lease change script is called for all existing DH

Hello,
I'm having a bit of a problem with the "cname" option in Dnsmasq. I have some
configuration options like these in dnsmasq.conf, where "host1" and "host2"
have IPv4 addresses from DHCP:
domain=philadelphia.example.com
local=/philadelphia.example.com/
cname=git.example.com,host1.philadelph
ame to host.cityname.dcpx.org and an A record for

Hello,
I would like to to configure Dnsmasq so that when it receives a CNAME record,
if the target is in /etc/hosts, it overrides whatever else the public DNS
server says about that target and uses /etc/hosts instead. Is this possible?
After studying the manual, it seems like not, but I'm wonde
