Zen and the art of IPv6
Running Zen Internet with a Cisco router? You get a native /64 IPv6 by default—but request a /48 for proper subnetting. Enable IPv6, add Google’s DNS, and configure DHCPv6 PD with ipv6 dhcp client pd ZEN-PD. Test with ipv6.google.com. Clean, native IPv6—no tunnels, no hacks.
