CRON TIMES / DropCatching

[seanc]

Hi, All.

Im attempting to catch some dropped domains using some
nasty bash code i have written.

I've seen the figure "1000 in 24 hours" mentioned a few times,
is that 10000 emails i can send to the automation system?
or is that a 1000 whois lookups?

can anyone give me some hints at schedules/cron jobs times
they are setting? 1000 times in 24 hours doesnt really give me
much chance of beating anyone to the domain..

or am i completly missing something here?

Thanks all,

its 1000 failed speculative attempts at requesting a domain and then you're banned until the next day.

There is 216,000 queries allowed to the DAC per 24 hours (which is effectively a query lookup to see if has become unregistered or not.) (don't rely on that figure it's from memory).

"From 31st January the limits will be increased to a maximum query rate of 1,000 queries per rolling 60 seconds and a maximum of 432,000 per rolling 24 hours, recalculated every five minutes."

http://www.nominet.org.uk/other/dac/aup/

Once you receive the response that the domain is unregged then you send your request request as soon as you can to beat all the others who are doing the same thing.

If you miss it, there's another of your 1000 gone!

good luck.

Not being a catcher in anyway shape or form, just interested in this business. Can somebody in a "Idiots Guide" way explain the terms 'Speculative' query and 'DAC' queries and how these affect the catching of a domain? i.e. if you send a speculative request and the domain is unregistered does this then register it, or do you have to follow that up by a DAC query and then email request?

I just keep seeing these terms posted and havent a clue what your all talking about!

DAC is just a query tool Domain Availability Checker.

It's high bandwidth and everyone floods it with requests every few milliseconds to determine whether a name has dropped or not.

Nominet drops the names in a completely "random" fashion, let there be no dobut about that (the quotation marks!)

So dropcatchers are allegedly finding these patterns and flooding the system with requests when these domains are about to drop.

Once they receive a reply stating that it is free to register they rush their applications in by email in a predetermined format that is specified by Nominet.

First come first served.

If however, you are lucky enough to have Speculatively sent a register request at that exact same time and you beat their response times then you can get that domain instead.

Nominet makes that near on impossible because apparently speculative drops takes sooooo much more processing power to handle than 432 times the normal requests from a TAG that you are limited to 1000 speculative requests a day or 1 every 87 or so seconds.

The top software is now purportedly operating at less than 5ms round trip so you 87 seconds starts to look just a little dopey. not same game, not same ballpark, not same country!

To put the 5ms in perspective, your average perl script without any thought to speed may take 2 or 3 seconds. Starting up processes, sucking in files, opening sockets, regexes etc - these are all things that your average first script would take time doing. The pro's scripts do none of that!

If you want to compete you have a long

LOL - Trust me I have no intentions of even starting in this game! I can just about get an 'if' statement to work in Excel let alone start playing about with Perl scripts.

As I said in a different thread, I visit this forum daily because it simply interests me. Some may find this odd, but the knowledge I have learnt here has been made some good conversations at work and down the pub. You tell people that x domain was sold for £x.xx and the looks of shock horror! You can see them thinking of names that they could register! Anyway, back on topic!

OK so DAC, Speculative and the Email are three seperate processes?

Your using the DAC to see if the domain is available and then if it is the script triggers an email to be sent? So when do people use the Speculative request, on pre-noms? Or do you just send them in the hope that at that point the domain has become available?

So do the pro's use a perl script, but just a much better perl script ,or do they use something entirely different ?. I guess at end of day its all down to how much money you have to develop the right script, is it ?.

That was me a couple of years ago (actually it was detagged.co.uk until it fell over, then Acorn), now I have a TAG and I submit 215,500 or so DAC requests a day and I have caught (at least) one good domain and a lot of reasonable domains.

Be careful...
