Many believe that warnings about the perils of running out of IPV4 addresses can safely be ignored–that like the Y2K machinations of the last century, they are much ado about nothing. After all, you ...

The Internet Protocol (IP) developedduring the mid-1970s, is the backbone of a family of protocols thatincludes TCP, UDP, RIP, and virtually every otherprotocol used for Internet communications. The ...

In hindsight, we reached peak IPv4 two years ago. The good news is that IPv6 is doing very well—but not nearly well enough. Is the IPv6 glass 1 percent full or 99 percent empty? “Hi, I’d like to sign ...

Almost from inception, the adoption and usage of the internet have grown at a rapid rate. Various sources estimate a growth rate of around 9% per year to nearly 5 billion users in 2021, more than ...

It would have been so easy if the early Internet and TCP/IP network designers had made IPv6 backward compatible with IPv4. They didn't. In 1981, IPv4's 32-bit 4.3 billion addresses look more than ...

Many enterprises use OSPF version 2 for their internal IPv4 routing protocol. OSPF has gone through changes over the years and the protocol has been adapted to work with IPv6. As organizations start ...

In the early 1990s, internet engineers sounded the alarm: the pool of numeric addresses that identify every device online was not infinite. IPv4, the fourth version of the Internet Protocol, used ...

Twenty years ago, the fastest Internet backbone links were 1.5Mbps. Today we argue whether that’s a fast enough minimum to connect home users. In 1993, 1.3 million machines were connected to the ...

If you are using Internet or almost any computer network you will likely using IPv4 packets. IPv4 uses 32-bit source and destination address fields. We are actually running out of addresses but have ...

In this post, I will explain some of the basics that are easy to understand. Before we discuss the differences between IPv4 and IPv6, we need to know some of the basics of IPv4. Finally, I will ...
