Search Engines – find domain names that begin with "karath"

I know the first 6 characters of a domain name. I also know that the field is about palmistry!

I need a search engine that can search all valid domain names starting with "karath". It is therefore necessary to search all valid domain names on the Web with the search term "karath *".

It is better that I write a description of each area.

Is there such a search engine?
