Domain Checker can handle up to 100 million domain names. You can load the domain names using a TXT or CSV file.
How to speed up the process?
If you have a huge domain name list and want to speed up the process, please use the menu: Settings > Enable Multiple-Threading
The software will leverage all available CPU cores and the process will be much faster.
When multiple-threading is disabled, the software checks domain names one by one. In that case, you may follow the steps below:
Make sure Settings > Delay is set to "0" (seconds).
Split your large domain name list to multiple smaller files. (It's a good idea to make each file using different whois server. For example; one file for .COM domains, one file for .ORG domains.)
Run multiple instances of the software and assign one of the files to each instance.
How to avoid "Try Again Later" and "Bad Response" errors?
Domain Checker relies on online whois servers. If you check too many domains in a short time, you may get these errors. The number of domain checks per minute allowed by each whois server is different. For most TLDs you will not usually get these errors. If you are getting "Try Again Later" and "Bad Response" errors, please follow the steps:
Use the menu Settings > Delay
Try different values such as 1 second, 10 seconds or more. (On whois servers that allow few domain checks per minute, it's a good idea to set a high delay and have the program run for hours in the background.)
I've been using your domain checker for the last 5 months it is good but recently I found a problem with this application when I put expired domain the domain said bad response can you guys please help me out with it?
