As a quick update, I tried changing dhcp-range=192.168.1.1,192.168.1.99,static,48h
to dhcp-range=192.168.1.1,192.168.1.99,static,infinite Things slowed down a little and I’m seeing fewer log entries, but it still doesn’t explain why the 48h entry didn’t seem to work. I’m assuming 48h is a valid syntax? > On 24 Feb 2015, at 10:31 AM, Gavin Hill <[email protected]> wrote: > > I’m using dnsmasq on a Raspberry Pi as a DHCP and DNS server for my home > network.
