I know we were planning something to address this... what was that plan?
The old DNS database contains some 46,000 entries. Probably fewer than
500 of these are still valid.
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?
