The goal is to have every DNS entry belong to someone who is registered with the portal, so that when that person becomes inactive (defined as no longer keeping their portal registration current despite annual reminders), the DNS entry will also become inactive, and after a year or so, be expunged. That way we can reclaim addresses and also prevent the DNS from being full of obsolete data. What we have to work with is a database that has only the DNS information for the vast majority of its entries. For the past few years, it has also been recording the timestamp and author of the entry. So the plan in general (details are still to be worked out) is to convert entries which match registered portal users either in the hostname or in the author field. That will have the effect of leaving out most of the obsolete entries but should retain most relevant (active) ones. Database matching is always a difficult task. This will be a painful process, but as far as I can see, the only alternative is to have everyone re-enter their DNS data from scratch, which would be even more painful and disruptive. I'm open to suggestions as to better ways to do this. Thoughts? - Brian
