Not really ---

you write:
+-----------+----------------------------+------------+---------------------+
| domain | server | updated | lastupdate |
+-----------+----------------------------+------------+---------------------+
| YAHOO.COM | whois.networksolutions.com | 2002-06-12 | 2002-09-17 04:54:25 |
+-----------+----------------------------+------------+---------------------+

I thought, this was about *registrar* servers, not DNS. You won't get a registrar from DNS ??!
Or do you really 'whois' the whole zone?

Yes I do every domain. I try and keep my oldest record within
the same month.

whois without recursion:

Domain Name: YAHOO.COM

Whois Server: whois.networksolutions.com
Referral URL: http://www.networksolutions.com
Name Server: NS1.YAHOO.COM
Name Server: NS5.YAHOO.COM
Name Server: NS2.YAHOO.COM
Name Server: NS3.YAHOO.COM
Name Server: NS4.YAHOO.COM

Example case:

hoho.com gets removed from the zonefile

removed: sep 3 2002
added : sep 10 2002

10 - 3 = 7 days spread. Domain was available 6 days after it
was dropped in the zonefile. (Domains registered today, will
show in the zonefile tomorrow. So where the domain showed
up on the 10th, it was registered sometime on the 9th.)

That's all I was tracking.

I'm working on more advanced tracking techniques but it'll be
a while...

That won't necessarily show which domains dropped.

Let's imagine someone's domain expires and is removed from the zone file. Five days later he realizes his email isn't coming through, and renews. The domain is added back to the zone file, and didn't drop at all, but you've just included that in your average..

Hypothetically, at least half the domains that expire are renewed, so half your data is flawed..
