You need to ensure that the clients are sending the hostname in the dhcp 
request.  Your dnsmasq logs will show it, usually in /var/log/messages, and 
if you want you can enable extra logging for dnsmasq to show u exactly what 
options are being sent by the clients.

If i remember correctly Debian doesn't but i would have thought Fedora would 
have by default.

You can do it by adding "send host-name <insert hostname here>" to the 

Alternatively, you can just assign the static IP using the client MAC in the 
dnsmasq.conf.  You will have the MAC from the dnsmasq logs so you can just 
copy and paste.
