Hi there ,
I do not know if this is the right forum I put my question but I did not know where to ,

I am asking about Classful and Classless IP addresses scheme (for IPv4), which is implemented (deployed) now days (on the Internet ) and if they both are , how they are not conflicting with each other ( in other words : have the classful addresses been eliminated completely from the internet space or it stills used , if yes how it does not conflict with the classless )

I have checked lot of sites were talking about the differences between the two approaches but this is not what I am asking about

I hope I made self clear ,
thanks in advance
