Hi, we try our best to parse the whois server response and deliver the desired data. We are always trying to improve the detection formula. If did in fact find some improvements on the .ai domains.

Regarding .at and .de domains the whois server doesn’t always return metadata like created, updated or expired dates, that’s why we leave it blank.

If you want us to look deeper into it, please provide some domains and the tool that you got it to work with.

Best regards,
MASNathan
