Need Help plesk server lost connection from provider

[tommy67]

I have a major problem. As of 3 hours ago my provider has cut my connection due to hosting a compromised webserver. I have about 35 clients that will be without mail and need to get them in service so i can migrate to another server. My question to anyone that can help me (I am willing to pay) is... Is there any way to easily change the pri. static ip address that my provider has cut off and substitue it with another dns service.
I have a secondary static ip and a working fiber connection that i can use.

Thanks!
