How can I check domains avaibility from a list ?

[gdndd]

Hi everyone,

Quick question ... I have several lists with thousands of possible domains and I would like to find the way to check their availability ... Is there any tool available to treat big list of domains (more than 500 as Godaddy) ?

Thanks in advance

After reading your post I got curious myself as to other alternatives.

Here are some alternatives I found but do not know how good they are. Besides the ones below you can keep searching on Google for different ones.

#1 https://www.dynadot.com/domain/bulk-search.html
#2 http://research.domaintools.com/buy/availability-check/bulk/
#3 http://www.domainhole.com/bulkcheck/
#4 http://www.namestation.com/bulk-domain-search (Up to 1000 it says)

In the end the Godaddy one seems to make the most sense since you can buy the ones you like right there. I was reading anything over 500 at a time can be very slow and cost errors. Just paste them all in an excel sheet if you haven't already and do 500 at a time.

Yeah ... OK but the problem is that I have a list of more than 100.000 domains ... Do 500 at a time will tkae an eternity ... !

I've tried many free bulk checkers, and I've not bee very happy with them. Most of them are slow and unreliable.

I've purchased a small utility (domainwhoischecker dot com - not an aff) which gives me satisfaction. However I have not checked thoroughly the accuracy (I've tested on a few hundreds only). My utility is ok for com domains, and it varies for other tlds.

If you need a high accuracy, I suggest you check two times as I have seen real horrors with free utilities, especially for non .com.

Not really trying to spam or plug here, but my software has a Bulk Availability Checker in it which could handle 100k domains. It uses API's or WhoIs servers to check domain availability, and also supports a number of different extensions.

 

[gdndd]

What software ?

http://www.domainhole.com/bulkcheck/ is great and doing a nice job but it's very difficult to treat which one is available or not when you have 864 pages of results ... There is no filter...

Interesting, try writing their help/support maybe there is a way to make it happen.

have a freelancer code a small script that connects to the verisign whois server (whois.verisign-grs.com) via telnet to check if the domain exists.

I don't know if it is actually allowed to do this but i have done >200k lookups/day without getting banned. If you are doing this infrequently i think it is OK. But i don't know so try at your own risk.

Even when you aren't multithreaded you could do 100k checks/day from your desktop. Had no problem doing it this way.

It's perhaps 20 lines of code. I don't think that would be expensive to develop. Some freelancers might do this for $30.

I just found this website... https://www.domainsatcost.ca

There is no limit of domains ... But i'm not sure of the result... It's taking a lot of time treating a few hundreads..

Keep in mind - this will only work with verisign extensions. I don't even think it would work with CC and TV. Likely just com/net

Yes that's correct. Also other registries might not allow high volume look-ups. AFILIAS and .ORG servers ban me quickly if I try to do bulk queries.

For most ccTLDs doing a few checks seems to be OK. I wouldn't necessarily recommend hitting them like the .com WHOIS server though.

To query other extensions you can use exactly the same process but you need the address of the WHOIS server. Either you can look it up manually or what is even better is the use the service @ whois-servers.net

making a request to tld.whois-servers.net will send your query to the TLD of your choice.

for example:

sending "seguro.mx" to mx.whois-servers.net will return the WHOIS for seguro.mx

I have just tried this for a few random extensions. .ru,.mx,.at,.cc,.tv,.me,.jp,.com.br

It seems to work for almost any extension.
