I'm working on this but there isn't a real easy or fast fix atm... There is a problem with the script I wrote to show whether the server is online or offline. I moved to a 64 bit OS, the script won't run in 32 bit os anymore. I'll have a fix soon, and yes I know about this.
Those are probably not old IPs... if the IP is showing (like it is in that screenshot) then the IP is real... if it wasn't real the IP would read mystrixonline.com:5124 and mystrixonline.com:5128 respectively in both fields. Example:
Thain Extended server is at mystrixonline.com:5128 or Direct Connect at mystrixonline.com:5128
