Getting from here to there The Transition to IPv6 has been long, and slow. We have reached a stage where many networks are dual-stack, supporting both IPv4 and IPv6. But dual-stack is not the end game. The final picture is to just support IPv6, making everything easy again with only one set of firewall rules, one set of […] Continue reading →

IPv6 PD in the SOHO IPv6 has no need for NAT, however, there is a need for a Globally Unique Addresses (GUAs). Therefore your SOHO (Small Office/Home Office) will require a block of GUAs to use. You can either obtain the Block of GUAs from your RIR (Regional Internet Registry, e.g. ARIN for North America and Hawaii), […] Continue reading →

DNS makes it easy The Modern Internet requires only two things of the internet user: IP address DNS (Domain Name Service) What is DNS? A globally distributed and resilient database of names to IP addresses (both v4 & v6). Why do we need it? Because the sheer number of websites and other services on the […] Continue reading →

Distributed to Centralized How has IPv4 been able to continue to carry the majority of Internet Traffic (about 69% as measured by Google)? The quick answer is NAT (Network Address Translation), but there is more to it than that. Now we see multiple layers of NAT (e.g. at the home router, ISP, etc). Fundamental shift of […] Continue reading →

EdgeRouter X and IPv6 The year is 2020, IPv6 has been a standard for over 22 years. And amazingly enough, there are still networking products which aimed solidly at the IPv4 customer, such Ubiquity. I bought the Ubiquity EdgeRouter X, thinking it would be a nice addition to my IPv6 Test network. Basically it is […] Continue reading →

Jitsi: IPv6 Enabled In these times of Social Distancing, or more correctly physical distancing, the use of Video Conferencing has taken a big upturn. Unfortunately most of the commonly known solutions are still stuck in the past century by only supporting IPv4. Some apps like Zoom, don’t even work on an IPv6-only network. But fortunately, there is […] Continue reading →

Google IPv6 Stats Like many of us IPv6 advocates, I regularly visit Google IPv6 Statistics Page. Some have noted that over time, the increase of IPv6 users have tapered off, and others have predicted that IPv6 usage will not increase beyond 30%. One can attempt to infer much from Google’s statistics, not always correctly. When I look at […] Continue reading →

Christmas has come and gone, but the Christmas tree in the corner still has a few days left before we take it down. On the IPv6 Internet (the “other” internet that the IPv4-only folks can’t see) there is an IPv6 Christmas Tree that can be decorated with your IPv6 pings. By assigning 16 million IPv6 […] Continue reading →

IPv6 to the Rescue Your embedded device has been running great for the past few weeks, and now all the sudden, it can’t be found on the network. You can’t ssh into see what the problem is, it has just disappeared. Lots of reasons why this may have happened, perhaps the program hit a bug and crashed, […] Continue reading →

IPv6 Fun Everyone knows (by now) that IPv6 is an 128 bit address. And most know that the least significant 64 bits is the Interface ID (IID). That is 2^64 or 18,446,744,073,709,551,616 hosts per /64 prefix (think: subnet). But no one expects we will fill networks with that many hosts per prefix. IPv6 prefixes are […] Continue reading →
