I am really confused on what you want to do here. When you talk about a
RANGE what do you mean? Allocate more than one IPv6 address to a single
interface?
If so, have a look at the IPV6ADDR_SECONDARIES clause in the link you
included. I am not sure that you can use alias interfaces for IPv6. Put
that in the ifcfg-ethx file, not in the config for the aliases
(ifcfgx:y)

I don't think you can use alias interfaces for IPv6. It at least did not
work on my other (Fedora) box
IPV6ADDR_SECONDARIES on the device DOES work on Centos 5.3

You have a single address provsioned indeed 2001:470:103:1a::2/64
with a network part of 64 bits.
