Charter does not yet offer native IPv6 but they do have IPv6 via 6rd tunnels for testing. It mostly works but I’ve seen some weirdness with various v6 destinations. Thumbnail images breaking on Facebook periodically and things like that.
I have this working on a Cisco 881W running IOS 15.3(2)T with the advsecurity license.

Set up a DHCPv6 pool:
ipv6 dhcp pool home-pool dns-server 2607:F428:1::5353:1 dns-server 2607:F428:2::5353:1 domain-name home.example.com
interface Tunnel0 no ip address no ip redirects ipv6 enable tunnel source FastEthernet4 tunnel mode ipv6ip 6rd tunnel 6rd prefix 2602:100::/32 tunnel 6rd br 22.214.171.124
Routes & general-prefix:
ipv6 general-prefix DELEGATED_PREFIX 6rd Tunnel0 ipv6 route 2602:100::/32 Tunnel0 ipv6 route ::/0 Tunnel0 2602:100:4472:A501::1
