IPv4 Addresses Are Now Becoming Obsolete

IPv4 addresses are now becoming obsolete. If you have taken any computer networking subjects before or other similar computer networking trainings, then you might be familiar of what IPv4 is. To put it simple, IPv4 sets the current rules that govern how data is sent across the internet. IPv4 IP addresses are comprised of 32-bit numbers where there are almost 4.3 billion possible addresses to use. With the extreme increase of internet users over the years (which also means more IP addresses to use), the 4.3 billion addresses have now been exhausted.

Here is an interesting article from CNet News which tackles the IPv4 exhaustion and what are the current possible moves done by authorities to cope out with the problem to continue the internet’s existence.

Today is the beginning of the end of the Internet as we know it.
That’s because the rules that govern how data is sent across the Net, a standard called Internet Protocol version 4, just became significantly more obsolete. The central Net authorities just handed out the last batches of IPv4 addresses at a ceremony today in Florida, beginning the cascade of scarcity that eventually will mean the computing industry must make the painful transition to the newer but incompatible IPv6.
It’s not an urgent problem for average consumers with broadband or even for many businesses with lots of servers. But it is a problem of unprecedented magnitude since ultimately it involves anything that touches the Internet, from the lowliest smartphone to the most powerful router shuttling data packets.
“This is the first definitive sign we are going to have a completion of IPv4. We’ve run out of the pool at the central level,” said John Curran, chief executive of the American Registry for Internet Numbers (ARIN), a group that received one of the last batches of IPv4 addresses. “It doesn’t mean there are no IPv4 addresses available. This is not the absolute end, but this is the definitive point where people know that we are indeed going to run out of IPv4 addresses and that they need to begin the planning for how to operate their businesses without receiving additional IPv4 addresses.”
Consequently, a lot of changes will arrive in coming days, months, and years. Here’s a look at what’s happening as the tech industry grapples with IPv4 exhaustion and the transition to IPv6.
