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 ...

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 ...

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 ...

I’ve written about IPv6 address design previously, and in that post I briefly touched on the fact that our long-ingrained habits of IPv4 address design can lead us astray when working with IPv6. I’d ...

Table 1. This table illustrates subnet masks. The number after the “/” in the CIDR notation indicates the total number of IP addresses available. Click here to see an enlarged diagram. Understanding ...

We found several utilities to help calculate IP subnets, subnet ranges, and CIDR addressing. IP Subnet Calculator (free) is a good, basic subnet calculator that shows available subnets based on IP ...

Subnet Mask divides the IP address into two segments and informs the computer which part is the network bit and which one is the host bit. For example, if there is an IP address: 192.168.0.1, it will ...

My book I'am reading IP fundamentals has gotten a bit confusing when getting combining several subnets which uses more bits for it's subnet number into one single ...

If computers in an open network talk freely with one another and two computers start talking at the same time, you have a “data collision.” Collisions may be arbitrated via Carrier Sense Multiple ...
