In many ways, networking is a mature, stable industry, based on established technologies like Wi-Fi and Ethernet, which just celebrated its 50th anniversary. But networking vendors are constantly innovating to keep pace with skyrocketing volumes of traffic that need to move securely and reliably across complex multicloud environments.

The operator played a critical function in establishing a global telephone network where any phone could talk to any phone. And when you authorize any device to join your home network, your network and your device are smart enough to automatically configure themselves to use your ISP's DNS service. But guess what? They get data.

If IoT devices supporting IPv6 over Low power Wireless Personal Area Networks (6LoWPAN) are introduced, the potential for larger DDoS attacks compounds. These sensors would be deployed in a Machine to Machine (M2M) network, but could utilize 6LoWPAN to connect to the internet. After all, there is strength in numbers.

Along with Transmission Control Protocol, a person’s IP address is what lets their computer communicate with their Wi-Fi network. First of all, your Internet network is composed of four distinct parts, including something called a data link layer. Here’s how to tell apart the following IP addresses: IPv4 and IPv6.

The naming system that we are all most familiar with in the internet is the Domain Name System (DNS) that manages the naming of the many different entities in our global network; its most common use is to map a name to an IP address, but it also provides facilities for aliases, finding mail servers, managing security keys, and much more.
