You should just be able to ask the registries to remove the delegations in a sane world as per RFC 1033.
COMPLAINTS These are the suggested steps you should take if you are having problems that you believe are caused by someone else's name server: 1. Complain privately to the responsible person for the domain. You can find their mailing address in the SOA record for the domain. 2. Complain publicly to the responsible person for the domain. 3. Ask the NIC for the administrative person responsible for the domain. Complain. You can also find domain contacts on the NIC in the file NETINFO:DOMAIN-CONTACTS.TXT 4. Complain to the parent domain authorities. 5. Ask the parent authorities to excommunicate the domain. If that doesn’t work go to the local magistrate an seek a court order for the delegating records that point to you to be removed. Then serve the court order on the registries. You are NOT required to follow whatever dispute resolution process that has been worked out between the Registries, Registrars and Registrant as you are NOT party to that contract. Your lawyer should be able to workout exactly how to to this. > On 25 Jun 2018, at 6:30 am, Alex <mysqlstud...@gmail.com> wrote: > > Hi, > We had a former customer who parked about 300 domains with his > registry on our server but is no longer a customer and hasn't moved > his domains.
