An Introduction to Different IP Classes

With the explosive launch of the world’s mobile networks we were facing the prospect of imminent IP address exhaustion. Yes there were only so many IP addresses created and allocated to hosts, and Internet service providers. The long term solution to  address IP address depletion became a serious concern.

Out of this effort came version 6 of the Internet Protocol, or IPv6.
