IPs are dynamic, not static.
That said, they do stay fixed for a long time.
In my opinion, Virgin Media should not give you a new IP.
This would pass your DDOS issue on to the poor person who gets your IP address.
They don’t deserve your problem.
You need to get this resolved by understanding how you arrived at this situation. Which service are you using where you have upset someone?
