[Dnsmasq-discuss] Static DHCP clients are not answered for in DNS requests

[Petr Menšík]

This situation should be supported and working. But if those hosts do 
not use DHCP to "activate" those names, you have to use different option 
for them. Use --host-record instead, like:

dhcp-host=192.168.10.203,mediapi
host-record=proxy,192.168.10.61

I think dhcp-host does not care for the order of name or IP. You can 
swap them to have single way defining them:

dhcp-host=mediapi,192.168.10.203

Not sure host-record does not care for the order of addresses and name.

dhcp-host is not resolvable until that address is assigned. That is by 
design. If you need name to have static address, then host-record or 
/etc/hosts is the way to go.

Cheers,
Petr
