I use Comcast IPv6. I've had the same IP address IPv6/60 for about six years now.
One gotcha is that when I replace the firewall, I gotta make sure I keep the same ethernet MAC address to avoid re-IPing on the IPv4 side (the line in my FreeBSD firewall's config is "ifconfig_ix0="DHCP ether 00:0d:b9:48:92:48".
The other gotcha, for IPv6, is I have to migrate my client DHCP Unique Identifier (DUID) (`/var/db/dhcp6c_duid`) to my new firewall to retain my existing IPv6 subnets.
