You simply can replace the ifup-ipv6 and network-functions-ipv6 script with ones that serves your needs. I found them available at: http://cvs.deepspace6.net/view/*checkout*/initscripts-ipv6/common/etc/sysconfig/network-scripts/network-functions-ipv6 and http://cvs.deepspace6.net/view/*checkout*/initscripts-ipv6/common/etc/sysconfig/network-scripts/ifup-ipv6 I didn't check exactly what is changed in those files, but they do have the necessary functions to add a range and it did add a range when specified like: IPV6ADDR_SECONDARIES="2001:4830:1128:4200::2/64 2001:4830:1128:4200::3/64 2001:4830:1128:4200::4-90/64" eth0 Link encap:Ethernet HWaddr 00:30:18:B0:C0:91 inet addr:10.8.9.248 Bcast:10.8.31.255 Mask:255.255.224.0 inet6 addr: 2001:4830:1128:4200::88/64 Scope:Global inet6 addr: 2001:4830:1128:4200::77/64 Scope:Global inet6 addr: 2001:4830:1128:4200::66/64 Scope:Global inet6 addr: 2001:4830:1128:4200::55/64 Scope:Global inet6 addr: 2001:4830:1128:4200::44/64 Scope:Global inet6 addr: 2001:4830:1128:4200::33/64 Scope:Global inet6 addr: 2001:4830:1128:4200::22/64 Scope:Global inet6 addr: 2001:4830:1128:4200::11/64 Scope:Global inet6 addr: 2001:4830:1128:4200::89/64 Scope:Global inet6 addr: 2001:4830:1128:4200::76/64 Scope:Global inet6 addr: 2001:4830:1128:4200::67/64 Scope:Global inet6 addr: 2001:4830:1128:4200::54/64 Scope:Global inet6 addr: 2001:4830:1128:4200::45/64 Scope:Global etc.... Those replacement files did not appear to cause any new issues on my CentOS 5.3 server.
