ipv6gen is handy for visualizing different possible addressing scenarios: % ipv6gen -s 4 -l 2607:f118::/32 48 2607:F118:0000::/48 2607:F118:2000::/48 2607:F118:1000::/48 2607:F118:3000::/48 2607:F118:0800::/48 2607:F118:2800::/48 % ipv6gen -s 4 -l 2607:F118:2800::/48 56 2607:F118:2800:0000::/56 2607:F118:2800:2000::/56 2607:F118:2800:1000::/56 2607:F118:2800:3000::/56 2607:F118:2800:0800::/56 % ipv6gen -s 4 -l 2607:F118:0800::/48 64 2607:F118:0800:0000::/64 2607:F118:0800:2000::/64 2607:F118:0800:1000::/64 2607:F118:0800:3000::/64 etc. Steve _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
