First of all let me clarify that I am programmer and that my knowledge in system administration are limited ( I know more than that limited spectrum but I wouldn’t trust me on those ). This idea arose out of two deferent needs , I have a dedicated server in one hosting company with only two IP’s and I am thinking to rent two more per month because I don’t want some of the accounts there to have the same IP’s resolving name servers as the others. The second need is that I am thinking to change hosting company at all and I have seen in the past that when you change name servers can take a while.
I will express my thoughts and please correct me if I got it wrong. It could be a service – company that would rent IP’s and redirect them to what ever IP you would like, more over you could adjust the name servers of a domain to point to that IP. In that way when you change a hosting company for example you wouldn’t have to change IP’s in your name servers. Are there companies providing that ? And with what cost in resources out of the redirection process?
