@vikram1583 What do your logs look like? Are you extracting from fields that already identified websites or email addresses or do you have a mess in your logs that you need to identify the pattern first and then the TLD? Are these URL's fully qualified, like https://www.example.com/, or are the more like example.com? Do they end at the TLD, or continue with parameters/directories/etc.? Details and a log sample will go a long way in people being able to help you efficiently.

@vikram1583 I maintain that this will go better with more details and a log sample. Please edit your question with a sample log (scrub for anything sensitive). Some of these proposed solutions aren't successful against patterns such as:
https://answers.splunk.com/answers/806969/need-rex-help.html (where the valid TLD is com)
www.example.wanggou (where the valid TLD would be wanggou)
etc.
