My last line within that is 10700061.

According to my import there are only 10700025 unique names, the discrepancy appears to be duplicates. How can that be?

e.g. domainfamily,co.uk on line 7013085 and 7010933. Albeit that the first one has uppercase "D" whereas second is lowercase, can someone please confirm I am not imagining this?

http://www.nominet.uk/whois/?query=domainfamily.co.uk#whois-results - probably a special case given who it's registered to and no expiration date.

I did see who it was registered to (haven't checked the others) but even so I cannot think of any valid reason why there should be a duplicate.

There is an exception and unsurprisingly it's registered to the registry without an expiration date. I probably don't need to understand why under those circumstances. You might want to check the others and the reasons for those might become self explanatory too. Is this only within the database dump rather than the zone?

I haven't processed the zones yet, so yes just the dump, I am currently in the process of identifying the others.

Not a problem for me as I'm using domain+extension as a primary key (was just domain, hence why I was originally 1million short!) so I won't end up with duplicates, I was just surprised that my count wasn't an exact match.

I'm sure tomorrow's file will be correct

They are all same registrant and most seem to have a theme (connection to registrant is not obvious) and most also expire on Thursday

What on earth are you guys going to do with this data anyway?

There's so much of it with the majority being worthless I don't think I'll bother.

Most are going to run it through the dac to create absolute drop lists. If you can't code, its almost useless to you other than to try and find potential buyers.

There are a few other uses too, don't wanna help potential rivals

The same as the other zone files for me, to keep my DNS history site updated. I'm sure Nominet will also be pleased with the drop in domain probing DNS queries

Add the unknowns to the 460 million or so active and deleted domain names tracked here amongst other things.
