One of my servers has been hacked. The following problem has appeared. When migrating the hacked server (1) to a spare server (x) there is no problem at all. However, I do want my customers to be redirected to the right server. The spare server is located on a diferent IP in another network so transfering the IP is not an option. A friend of my suggested to change all the NS records in BIND however, that takes time. There are 2 options: 1 is that every record is being changed (more than 500) or that I replace them al. Somebody can tell me if there are other options?
