Can I delete all submissions for a certain IP address

We have a form with around 50k submissions. However, one spammer (different emails but same IP address) accounted for around 15k of those submissions. We have since installed a captcha and prevented new spam entries but we are trying to remove all of the old submissions from the total number. I've seen that you can delete all submissions within a certain time parameter, but can you delete all submissions of other search results such as domain or IP?

For example, I would want to delete all submissions ending in the domain @fastergmail.com but leave all other submissions and/or delete all submissions with the IP address xxx.xx.xxx.xx but leave all other submissions.

Thanks

Unfortunately, it is not possible to search for submissions using IP address. However, you may search by using email address or part of email address so that you may select these entries and delete them manually.

Please make sure that you are deleting the spam submissions since the submissions deleted are gone forever and cannot be restored. It is also recommended to take a take a backup of your submissions before you delete the submissions.

Hope this information helps. Thanks!
