Return a CNAME record which indicates that <cname> is really
<target>. There are significant limitations on the target; it must be a
DNS name which is known to dnsmasq from /etc/hosts (or additional
hosts files), from DHCP, from \fB--interface-name\fP or from another
.B --cname.

DNS record which is known to dnsmasq and NOT a DNS record which comes from
an upstream server. The cname must be unique, but it
is permissible to have more than one cname pointing to the same target. Indeed
it's possible to declare multiple cnames to a target in a single line, like so:
.B --cname=cname1,cname2,target
