--------------------------------+------------------------
While testing. I noticed a mismatch between the IP range written in
/tmp/etc/dnsmasq.conf (which ends at 10.177.31.253) and the one calculated
by ipcalc.sh (which ends at 10.177.31.254)
{{{
root@OpenWrt:/etc/config# ipcalc.sh 10.177.0.1 19 129 8061
IP=10.177.0.1
NETMASK=255.255.224.0
BROADCAST=10.177.31.255
NETWORK=10.177.0.0
PREFIX=19
START=10.177.0.129
END=10.177.31.254
}}}
Yet when configuring dhcp
{{{
root@OpenWrt:/etc/config# cat dhcp
...
config dhcp 'lan5'
option interface 'lan5'
option start '129'
option limit '8061'
option leasetime '1h'
...
}}}
the resulting dnsmasq config file:
{{{
root@OpenWrt:/etc/config# cat /tmp/etc/dnsmasq.conf
...
dhcp-range=lan5,10.177.0.129,10.177.31.253,255.255.224.0,1h
}}}
the IP range in /tmp/etc/dnsmasq.conf ends at 10.177.31.253 instead of
10.177.31.254 as calculated by ipcalc.sh
