In 2.55 we could say in dhcp-optsfile: tag:aconcagua,tag:vl160,69,hoggar
However 2.57.1 complains: "bad IP address at line 21 of /etc/dnsmasq/dhcp-options" Is this a bug in 57.1 or was it a bug in 55? rfc2132 says the length must be a multiple of 4 but doesn't say it must be the ipv4 address... The changelog doesn't mention anything.
