if I would need an additional IPv6 address I'd just add IPV6ADDR_SECONDARIES="ipv6addr" to this file; if I would need an additional IPv4 address this works only by a virtual device e.g. eth0:1 like this:

That's not true, you can add ipv4 address to the interface in the same way:

| IPADDR2=172.17.170.101 | NETMASK2=255.255.255.0

There is no need to create a virtual network device.

ah ok, and the other values?

IPADDR2=192.168.1.10 BROADCAST2=192.168.1.255 <-- NETMASK2=255.255.255.0 NETWORK2=192.168.1.0 <-- GATEWAY2=192.168.1.1 <--

in case they don't match the first IP address?
