[Dnsmasq-discuss] Lease duration for hosts without names

[Jay Guerette]

I should have been more explicit in my ask. I know how to fix it but I 
want to prevent it in the future. When I'm not around I want my network 
to work without intervention.

Most people don't know what a MAC is, don't know where the setting is, 
and may not react well to "you have to disable privacy if you want to 
use my wifi". The smaller pool size & longer lease length could be 
considered short-sighted or self-inflicted. I didn't anticipate guests 
requiring 4+ IPs on my network each and constantly acquiring new ones 
without releasing the old ones.

I think that hosts that don't provide a name are either mis-configured, 
poorly designed, or just privacy focused. We already have 
'dhcp-generate-names' that identifies these hosts, I'm wondering if we 
could extend the concept to allow you to add a tag to such hosts so that 
specific policies could be applied.
