PodSnacks: Addresses

Sometimes we go for deeply technical topics. Sometimes we just go back to basics. Today is a back to basics day. In today's PodSnack, Dave takes you through the concept of addressing . You can listen to (or download) the PodSnack by clicking here Read More...

PodSnacks: Variable Length Subnet Mask (VLSM)

An exploration of the IP address and subnet masking , is not complete without a look at variable length subnet masking (VLSM). Michel explores the role of the mask in partitioning a network, and the flexibility introduced by being able to vary the length Read More...

PodSnacks: IP Addressing

Let's shift from the OSI Reference Model to a particular protocol suite: TCP/IP . There's lots of ground to be covered there, so we need a focus. We're going to narrow in on Layer 3, which is mostly about the Internet Protocol (IP), the packet Read More...

PodSnack: Dynamic Host Configuration Protocol

Ever wonder why that laptop of yours works regardless of where you go? You plug into the Internet at home, in the office, in hotel rooms, and it always seems to know what it should use for an IP address . Today, Trevor and Michel discuss how that magic Read More...

PodSnacks: Broadcast, Multicast, and Unicast

PodSnacks: Uniform Resource Locators (URL)

We use them every day: those pesky strings of text that we type into our browser address bar. They are known as Uniform Resource Locators , or just URL. Some of them can be very convoluted. So what do they mean? How come I type just www.hill.com and end Read More...

PodSnacks: Static vs. Dynamic IP Addresses

I am on vacation this week, so I thought I'd do a bit of a retrospective week. Some of you who are new to the series will be hearing these for the first time, but they are drawn from our library. This one was our first PodSnack ever, in which Trevor Read More...

PodSnacks: Automatic Private IP Addressing

Today we wander back up to Layer 3 , specifically to an issue associated with IP and IP addressing . Sometimes, people connect their computers together in small networks in an ad hoc fashion, and amazingly enough the computers seem to be able to find Read More...

PodSnacks: Electronic Numbering

A couple of days ago we talked about the Uniform Resource Identifier (URI). As we move towards a packet-voice world and protocols like SIP , URIs will become more important. So too will Electronic Numbering (ENUM). This is an approach that promises to Read More...

PodSnacks: Uniform Resource Identifier

Some time ago we talked about the URL (hard to believe it was back in January, over 160 episodes ago) and learned how it is structured and what it is used for. As it turns out, a URL is only one form of a larger concept known as a Uniform Resource Identifier Read More...

PodSnacks: Address Resolution Protocol

So now you know what IP is (if you tuned in to yesterday's PodSnack on the Internet Protocol . IP is the glue that holds the Internet together. Layer 3 . Packetizing protocol. Datagram . Connectionless . But the whole point of IP is that it rides Read More...

PodSnacks: IP Addressing - Static Vs. Dynamic

Happy New Year! In the first PodSnack of the new year, Trevor and Michel describe the difference between static IP addresses and dynamic IP addresses and explore when it might still be advantageous to have a static IP address, especially on an Internet Read More...
