I may want to give up/abandon a Domain Name that has old Nameserver names assigned to it.
How can I start with that domain (example.com) and find out:
1) What name servers EXIST (ns1.example.com etc)
2) Of these name servers, which ones are in use ... meaning, I want to know if I delete all name servers for this domain, and even give up the domain, what Websites might stop working
Any Mac, Linux, or online/server-side solution would be wonderful, though if you only have a Windows solution, I am sure I could find a Windows PC around here somewhere
Thx in advance all!
