Hello,

We have created an script which tries to register domain names once per second.

But we should use a whois server which allow us to get queries for at least 20 domains, once per second.

Do you know any one which allow that? What should we use to do that?

And some whois servers dont update once a doman name get available to register, those are not usable for us.

Checks aren't really the purpose of a WHOIS server.

Just find a registrar that will allow you to use their API check.

whois lookups arent checking domain availability as whois data is held at registrar NOT the registry (for com/net.. some registries do contain both). I think you're approaching your problem wrong. If you are trying to drop-catch manually (or through api) to compete, I will say this upfront... you don't have a snowball's chance in hell ;) But if you want to try anyways you will need to use a registrar's API that allows you to directly check in realtime the availbility of a specific domain name.

Hello,

Do backordering companies know something more than others? (We know all apparent things about domains and expiration and deletion dates and times)

We have powerful programmers here and powerful servers too, but the only thing is a whois server and or domain checks from API`s.

I think that wont be usable to use some registrar`s API, because of the following reasons:

1) Some of them like ResellerClub dont offer realtime whois, and that updates some hours after changes.

2) As our system should check domains at least 1 time per second, That requires 1 powerful server for only 5 domain names.

What do you offer? What do they do to backorder domains?

Do you know any written scripts or desktop programs about that?

Think thousands of times per second. For com/net drops verisign has special drop threads that only registrars can use during the drop process to reduce the effect of the extreme hammering of the registry during that time to get the best names. Each registrar is only allocated a certain number of drop threads (why you see companies like pool/snapnames buying/affiliating with tons of registrars to maximize chances).

The best programming in the world won't save you, you NEED a registrar to drop chase for the good stuff.

Hi kohashi,

Thanks alot for your helpful answer.

Is it possible to let me know what should i ask registrars to do for us? and explain about that?

I`m not sure what should we get from them.

You will have to convince (pay) them to use their connection and run software directly basically. I have never owned/run a registrar so I can't get into any specifics, but verisign has a special drop pool that registrars are required to use to catch expiring domains afaik.

Hamid, even partnering with a registrar won't work if you have your own registrar credential. The big players in the drop club have several hundred cred's just to chase the dropping names in the batch pool. Each cred is allowed but not guaranteed up to 4 connections each. eNom for example is approaching 400 creds so if they each get the max of 4 connections they are using 1600 direct connections. They run at a rate of several thousand requests per second. Even if you have your own registrar cred there's no way you can compete. If you hit any open API's to try to script the dropping domains you will be shut down because Verisign has a cap on the number of times a registrar can try to register the same domain. If the registrar doesn't shut you down the registry will block the registrar's connections. About the only hope there is today is to join one of the drop catcher or "auction" services for expired domains. Unfortunately you are about 5 years too late in entering the expired market.

Hi sellmhi,

Thanks alot for your help.

I`m monitoring many domains at a time and register those manually, but we lose more than 90% of them.

I`m not going to start a backordering company, i`m going to backorder my monitoring list domains which will be around 50 domains at a time.

Pool / SN / eNom, each has many domains monitoring and try to get each time, but we have only 50 domains at a time, so can we imagine to backorder those names sooner than enom and others if we get partnering with a registrar only?

Hamid, the number of domains that you are trying to get is irrelevant. The registry releases the domains in order of expiration so for example you have 1 domain that you want. You can roughly calculate (as a registrar) at what point in time the domain will drop. Each registrar is trying to calculate to the nano second when this will occur for the same domain that you want. Some are better than others and will cover a "time range" for the domain with great success. If you are able to calculate this precise time you are still competing with all of the registrars which run an auction or backorder system. They are constantly moving through the list of dropping domains to try to stay in synch with the order of the domains becoming available so the problem still remains, their thousands and thousands of requests per second versus your 10 or 20. How good is your luck?

Hello,

As you told something about connections, I thought when eNom has 1600 connections but 10000 domains to backorder, we`ll have 4 connections (which will get from a registrar) but 20-30 domain names. that should be the same, not?

How do they calculate the file exactly? As i have heard, most of domains releases at 3:00PM EST, is it right?

If no, How do they calculate deletion time exactly? have they any tools to do that?

there is a list with the order the names delete each day.
