QUESTION: My question is if internet service providers and cell phone companies retain  a log for ip assignment logs on subscribers and if this logs are a central log for the network and all subscribers in order to allocate ip address assigned at a given date ? Or if those logs are kept individually for each subscriber? And how long this logs are retained on average by i.s.p and cell phone companies  before being purged or overwrited?

Each ISP keeps log of assigned IP, and duration for which the logs are preserved varies ISP to ISP.

Are you looking it from forensics perspective or from security point of view?

If you can share objective then I would be able to provide more details.
