Yes, the MAC should be fine as it is as long as the IP addresses are changing. You should keep a notepad and log each and every IP address used to login your eB accounts. It's very important to keep track of your IPs, you don't get a second chance if you make a mistake. Use the same IP for two different eB accounts and they are linked, if one goes down they both will.
