Yes, I am needing to know what the total number possible IPs in the public IPv4 space.

I'm not sure where to even get a neat list of all the IP address ranges, so could someone point me to a resource to calculate this myself or calculate the total number of IPs for me?

Also, by Public IPs I mean not counting reserved or private-range IP addresses.. Only the ones that can be access through the internet.

And too many addresses in this post.
