A legal statement you file with a registrar to contest a DMCA takedown notice and restore a suspended domain. You're asserting the takedown was wrong—either the content is legal, the sender has no real claim, or they're abusing the process.
When a registrar gets a DMCA takedown, they can park your domain, suspend it, or nuke it. You have ~10 days to file a counter-notice swearing under penalty of perjury that the content doesn't infringe, or that you have a legitimate legal defense. File it, and the registrar *should* restore your domain within 10–14 days—unless the claimant sues you in court.
The catch: filing a counter-notice puts a target on your back. The original claimant can pursue actual litigation. Most registrars follow the safe harbor rules strictly, but some use takedowns as a pretext to seize domains without real review. At bunkerdomains, we don't auto-comply with DMCA notices. We notify you, give you time, and require the claimant to either back off or prove their case in court—not in our abuse ticket system.
