Thanks for your reply. Currently we have a /26 range of IPv4. So we have eth0:1...eth0:59 We need that same with IPv6 since we have a /48 and we need to have all IPv6s available for usage. I tried to use same ifcfg-eth0-range0 same config by adding: IPV6ADDR_START= which seems not to work for this. None IPADDR_START too. We need a simple way to have our virtual eth's with IPv6 all the range available.

Or, its 65536 /64 subnets of 18,446,744,073,709,552,000 hosts each. -- john r pierce 37N 122W somewhere on the middle of the left coast

An interface can have multiple addresses in V4 or V6 managed with the "ip" tool rather than "ifconfig."> We need that same with IPv6 since we have a /48 and we need to have all > IPv6s available for usage.If you need additional IPs for HTTPS virtual hosts or something like that, it looks like you can use IPV6ADDR_SECONDARIES in the ifcfg file.

Yes I confirm...its a /48 (this guys are crazy here at my work...).
