Well! New year, new podcast. I’ve been fortunate enough to move from “most frequent guest” to full-on co-host of IPv6Buzz, and I am pretty freakin’ stoked if I am being completely honest!
We’re out of the gate with a bang, too. This first podcast of 2025 (and first with me as a co-host) is diving right in with some bold predictions:
IPv6 adoption should cross 50% in 2025.
We discuss the implications and significance of IPv6 adoption reaching this milestone.

Over the last few years I have pulled back from the social networks and refocused in a way that has allowed for more time not doing tech. Overall this has been an extremely healthy choice that has only strengthened my desire to learn new things, experience different ways of thinking, and expand my overall vision past technical endeavors. This has led to some enlightening thoughts surrounding how not hyper-focusing on one thing is, in reality, a very good thing overall, and contrary to what social media may imply, will only serve your overall well being, which in turn can fuel passion toward things that can actually be beneficial career-wise.

Once again I was fortunate enough to be invited to talk with the experts on IPv6 Buzz about everything IPv6 and my experience with attending IETF 116. You can check out the episode here. Discussion mostly includes Discussions on multihoming IPv6, but we run the spectrum of addressing, documentation, and all of the fun topics! Give it a listen here or in your favorite podcatcher. https://feeds.packetpushers.net/link/19801/16106092/IPv6_Buzz_125_Unique_Local_Addressing_ULA_And_Other_IPv6_Topics_At_IETF_116.mp3

“Multihoming IPv6 is a pathway to many things some consider to be ……unnatural.” ―Darth Sidious, maybe. The current state of usability for multihoming IPv6 is fairly limited, and not terribly supportable. That said, it is doable, if you have the fortitude and hardware / software to make it happen. In this episode of MODEM, we get super nerdy about the current state of multihoming IPv6 and all of the gory details and exposed limitations.

IPv6 unique local addressing has been a popular topic over the years. From its humble beginnings, replacing site-local, to the surge of interest within service providers, enterprise, and casual users due to the wealth of content now available on IPv6 and the prevalence of availability within major consumer ISPs, it has become quite a polarizing topic in the technical communities that are diving head first into the modern, current networking protocol - IPv6.

So, you need a 100G router or switch, but are deeply concerned about:
CostPower drawCooling issuesPriceCapabilitiesMoneyAvailabilityCapEX The ever-increasing need for faster interfaces, and standardization in the WAN at 10G and 100G rather than 40G or 25G as an interface spec has dramatically increased the need for 100G hardware. With power consumption of most 100G platforms rising to ludicrous levels, and the accompanying cooling required to keep those platforms running smoothly keeping pace with the power draw, one may start to believe there is little hope for 100G for the small to medium size networks.

The future called and it wants more IPv4 space. As much as I am a staunch proponent of IPv6, I get the need for more IPv4. Cloud providers, enterprises, ISPs, they all need it to stave off the CG-NAT as long as possible. Well, some friends came up with a pretty straightforward way to get it - or, according to some “completely break the internet”. We recorded this episode with Dave Taht (who you may remember from our podcast on bufferbloat) and Seth David Schoen about some new drafts they wrote for the Unicast Use of the Formerly Reserved 240⁄4, 127.

Well there has been a lot of hubbub about IPv6 unique local addressing lately. You know, that address space defined by RFC 4193? The one that most folks think of as “RFC1918 for IPv6” (It’s not that)? Well, we recorded a podcast with Ed Horley over at modem.show to talk about it. Interested in how ULA is different than GUA (globally unique addressing)? Wanna understand what is broken about it (the list is significant)?

IPv6 has been a hotly contested technology for as long as I can remember. It has always been “a few years out”, or something “no one is asking for”, depending on who is asked. In reality, and like most things, the truth lies somewhere in the middle. IPv6 has been slow to appear for certain demographics of networking, but a long standing pillar in others. It just so happens that IPv6 is not being asked for because when deployed correctly most users just don’t notice that it is there - and that’s by design.

Back in January of 2016 a vain attempt was made to do a networking podcast called “non-blocking”. One episode was recorded - an informative conversation with Peter Phaal of sFlow / inMon. It was really fun to do, and was met as a reasonable freshman endeavor. In the making, however, there were a few thing that were made painfully obvious:
Scheduling a podcast is difficult. Getting the right people available at the same time is often a herculean endeavor in and of itself.

2 Jan 2021 seems like as good a time as any to start thinking about change. Change is inevitable. The only constant is change. Adapt or die. There are any number of stereotypical and cheesy mantras that can be chanted over a beating drum whilst sitting around a fire. However, saying them and coping with change are very different beasts. AsI have written in the not so distant past, most change invokes an inherent fear of failure and aversion to risk.

Today more than ever, networking has fundamental similarities. The days of routing IPX/SPX, AppleTalk, Banyan Vines or provisioning ATM and Frame Relay links are moving into the past. Most networks are now based on ethernet*. Most run at least IPv4 as a routed protocol. They leverage similar connectivity techniques such as an interior gateway protocol, a layer2 mechanism such as VLANs or VPLS, and an identifiable border (e.g. an autonomous system).

For those that may not be familiar, The Brothers WISP is a last mile wireless and Mikrotik focused podcast (although they cover far, far more than just that). Recently, I had the pleasure of sitting down with them again, this time one on one with Greg, the mastermind behind all of it (or as I like to call him - “The velvet fog” due to his really smooth and polished podcast delivery).

Segment Routing. The technology that will likely cement itself (or already has, depending on who you ask) as the next evolution of carrier networks. Three years ago I was asked to participate in a very deep round table put together by the Tech Field Day crew and the only topic on the table was Segment Routing. Needless to say, I was enamored by the advantages that the raw technology provided, and thus far that enthusiasm has not diminished.
