Network devices use IP addresses and subnets to identify the source and destination of communications and manage network addresses respectively. IP addresses contain two parts: a network identifier ...

Today, the standard methods for moving the network/host address boundary are variable-length subnet masking (VLSM) for host addressing and routing inside a routing domain, and classless interdomain ...

A subnet mask is a number that specifies which parts of an IP address represent the host and network portions of the address. These masks are 32 bits in IPv4 networks and 128 bits in IPv6 networks. A ...

The last editionof this column discussed subnet masks and the nature of IP addressing. In this and the following column, we will begin discussing what subnetting means and how to do it. First, though, ...

In addition to IPv4 (often written as just IP), there is IP version 6 (IPv6). IPv6 was developed as IPng (“IP:The Next Generation” because the developers were supposedly fans of the TV show “Star Trek ...

IPv4 addressing is used to assign a logical address to a physical device. That sounds like a lot to think about, but actually it is very simple. Two devices in an Ethernet network can exchange ...

George Ou explains IP subnetting using his own graphical approach. It’s a great primer for students and a nice refresher for others. IP subnetting is a fundamental subject that’s critical for any IP ...

Have you learned to think and dream in hex yet? That is what you are going to have to look forward to as we transition to using IPv6. Because we will be working in hexadecimal numbers we may need a ...

This is the first of many technical blog posts I’m going to post on IPv6 architecture and implementation for a Microsoft Windows-based environment. I started off with a basic introduction of the IPv4 ...

Broadcast and video production systems are moving rapidly into the IP realm. Therefore, understanding IP basics is now part of the engineer’s toolkit. To understand how IP works, we need to understand ...
