I am currently working on a customer site and they have their Private IP address space set up to use a Public Class A IP address range. Could anyone advise why this would be done?
I appreciate that by using NAT they will translate the private (internal addresses) to the outside world (public addresses) but what is stopping a conflict whereby someone on the web registers the same public Class A IP address range for their web server and then when the internal host from within this organisation tries to get to that web server on the Internet it ends up going to Bob's PC within the company instead as it has the same address?
I guess if this particular company has been allocated this specific Class A address range by the relevant authority that knowone else should be able to use it in the public arena, however does this actually prevent someone from using it?
I am used to seeing private IP address space being used within organisations and then being Natted out to Public as it is written in all the course books etc
I would appreciate a discussion on this topic
