Hello,
Anybody knows good technics for domains catching?
Please define “domain catching”, if you mean expiring domains, use a service like GoDaddy which monitors and registers expired (past the grace period) TLD’s 
Looks like that. I know some fresh lists are being posted on the namepros forums . So I recommend you do some search there.
I assume you are referring to domains drop-catching, i.e. registering the domain exactly when it is released just before anybody else.
Unfortunately you won’t be able to do it in a DIY fashion because you need access to the corresponding Registry queue and only official Registrars have such an access. Furthermore the amount of requests and the number of parallel connections to the Registry that each registrar has are limited, consequently it is very unlikely they will lend it to you easily and/or for free.
There are some Registrars that are offering such a service for a fee, but because we are a Registrar I let the task of mentioning our competitors to other posters. Instead I would recommend Pool.com, they are not a Registrar, what they do is signing agreements with a lot of Registrars in order to use their registration queues and share the profit, which is an interesting approach for both participating Registrars a and of course for customers because their dropcathing success rate is extremely high taking in account they can count on a large number of parallel and simultaneous registration queue accesses. They are also predicting the exact day when a domain is released in a very accurate way.
Disclosure: We are in no way affiliated to Pool.com, however we lend them some of our Registry access queue when they need them.
