as I discovered recently a lot of domains of a certain organisation all have their A-Record set to the IP of a server that I own. The server currently does only host security auditing tools and does not contain a website. However I might want to host something with this IP in the future and do not want to be associated with the domain-owner at all. I already looked up the whois information and tried to contact the organization. I did not receive any reply. Is there anything I can do to get the domain owner to no longer use my IP?
I ended up deleting and re-creating the virtual-server which gave me a new IP. Not the best soltuion since someone else will now "pull this IP out of the hat" when setting up his/her v-server.
