I've written an internet-draft on the subject: http://tools.ietf.org/html/draft-howard-isp-ip6rdns-04 The latest update was to add a Recommendations section: The best option is for ISPs to delegate authority along with address delegation. Where users do not operate authoritative name servers, the next best option is dynamic DNS updates. Where dynamic DNS is impractical, the next best option is to dynamically generate PTR records when queried. In other words, when you do prefix delegation to a residential customer, generate records on the fly. Ask your DNS vendor to show you how. Wildcards work if all you want is a non-null response. I'm looking for support or opposition to this. I just can't see any better way to do it. Lee

Hi guys,
I am looking for operational experience here.
We have just turned up IPv6 in our "guest wireless", by way of using RA for address distribution and DHCPv6 for the DNS server address (stupid, yup).
Apart from the dhcp6 part seemingly not working on Juniper ISGs (or maybe it's my windows *and* that Ubuntu), I now see IPv6 addresses instead of names.
I as a networking droid have not much quarrel with that, but I am interested in how or whether at all others handle this.
Are you creating DNS entries somehow (reverse and, ultimately, forward), are you using BIND "generate" statements, are you using wildcards...or are you just ignoring this for the "dynamic boxes"?
Please enlighten me!
Elmar.
