Because the DHCP "name-server" attribute (option 6) carries only an IP
address and not a port, this isn't going to work. The DHCP clients simply
aren't written to configure DNS on any port other than 53.

the same host, one t

The default configuration of dnsmasq is to act as a caching proxy server
(this behavior of dnsmasq has existed before dhcp support). There are a
few reasons the proxying could fail, chief among them being firewall
rules. If that isn't the problem, increasing the logging detail may give

If by "alias", you mean a second A record for 84.92.49.234, then the common
practice is to use a hostname of mail.domain.tld

You're imagining the "reserved range".
The --dhcp-host configuration option of dnsmasq will reserve an address.
--dhcp-range=static will not.

Try removing the static dhcp-range entirely.
Reserved addresses don't have to be in a pool, just on a network where DHCP

Sounds like a search suffix is getting involved: After failing to find
myhostess. your resolver looks for myhostess.X.com. which finds the alias.
/etc/resolv.conf should contain the directives which control search suffix.

I think more consideration should go into the configuration command

counter-intuitive. After all,
dnsmasq doesn't use zone files. You can try with txt-record= (see the

Check if sending the DHCPOFFER fails (if for example, it is a renewal
packet and therefore unicast rather than multicast, and it can't find
a MAC address for that client because ARP is blocked). I think
checking the return value from `sendto` should trap this scenario.

Just use multiple dhcp-host lines.
Also, the order is
dhcp-host=[][,id:|*][,set:][,][,][,][,ignore]
That is, the hostname comes after the IP address. And the netmask

No. You must configure dnsmasq with an upstream nameserver which will
perform the recursive query.
dnsmasq is a server for your local zone (with DHCP integration, similar to
dynamic dns) and a cache. It is not a recursive nameserver.

That looks like a comment to developers. Seems a mistake if it's actually
printed at runtime.

DNS is the wrong place to implement this behavior.
Interception of TCP connections is done with packet rewriting rules in
iptables, and you'll need to set up your exceptions there also.

Existing scripts could definitely break, imagine one that just logs certain
environment variables plus the parameter. The new action values won't have
the right environment variable set.
How about both? Give the --tftp-script the same action parameter, and keep
actions unique, that way both opti
Since the PTR name contains the IP, by definition different IPs means
different PTR records.

Contacting DHCP servers is a task for a DHCP client, not a DHCP server.
There are a number of scripts available which will send a request and
listen to all responses (not just the first), generating an alert if any
unexpected nodes responded. Google "rogue DHCP detect".

Do you even need WINS if DNS lookup is working properly? I think it's
become completely redundant.

Check your log, see if the camera is reporting a wrong MAC, different
client-id, different vendor class, or something like that.
Or possibly the camera's bootloader is remembering its old address
(gotten before you configured your hosts file) and requesting a
renewal. Again, the log would show a
