When using dnsmasq as a DHCP server, unless you use the noping option
(and that is not recommended), the NET_RAW capabilty is required so
that dnsmasq can send ICMP packets. These are used to check an address
is not currently in use[1].  Docker enables this capability by
default. Podman runs containers with a minimal set of capabilities[3].
