Since we already have an ASN, its free basically. I already have one. Its at least a /32 and maybe a /28.

My upstreams support it, my ONTs support it but there isnt a nice ipv6 dhcp server with logging and a lookup interface that I have found yet. It probably exists but I don't know what it is.

IPv6 blocks are usually quite reasonably priced. You might even get them for free, if you're already paying maintenance on an IPv4 block (which are expensive to obtain these days)
