Updating whois information
If you enter an invalid top-level domain (e.g., example.qwert), you'll see "No whois server known for the given domain." You can specify a subdomain in a query (e.g., xyz.example.com).
There isn't any worldwide repository of whois records.This means that a minor change to any of the above-mentioned fields in the owner contact information, will, legally speaking, initiate a change of ownership.Take a look at the example below, which involves a simple update to the organization name field: Both the old and new Registrant will have to approve of this change.It's really not useful to perform whois queries on subdomains.Internationalized domain names (IDNs) can contain UTF-8 characters in addition to ASCII. Click on "IDN Conversion," which will take you to a page with a conversion form.
