If there are two things to learn from all the new information presented at last week’s (October 24–28, 2016) RIPE-73 meeting in Madrid/Spain, then it’s that IPv4 is quickly going down the drain and IPv6 deployment are still in many areas lacking to replace it.
BIVBlog #36: News from RIPE-72
The RIPE-72 meeting in København (Copenhagen (Denmark)) from March 23–27, 2016 showed a remarkable prominence of IPv6 related matters. Yes, we (as in “the Internet community”) do make progress, and the presentations clearly show so, which is a Good Thing[TM] to happen. Not quite as inspiring is the fact that the IP address market is […]
BIVBlog #35: Thin Clients and Beyond
If thin clients like the SunRays I’ve shown in BIVBlog #34 were so appealing to users, system administrators and managers alike, then why did they stay a niche product? And why does nobody care about them anymore? The answers to these questions are interesting not only with regard to thin clients, or SunRays, but to […]
BIVBlog #34: Playing Around with SunRay 1 Thin Clients
During an IPv6 training I held last year I was given two Sun Microsystems SunRay 1 thin clients. I give them a closer look, explain why they caused so much excitement when they hit the market, and tell about the problems I ran into trying while trying to get the server side to work.
BIVBlog #33: ICMPv6 (ICMP for IPv6) Filtering
Filtering ICMP packets for IPv6 (or ICMPv6, or ICMP6, depending on the texts you read) is somewhat daunting at first. But once you’ve thrown your fears and possibly dogmatic attitude towards ICMP out the window, setting up a reasonable packet filter configuration is actually fairly straightforward. This video is basically a translated re-run of a […]
BIVBlog #25: Highlights from RIPE-68 and about my secret project
Here are my personal highlights from last week’s RIPE-68 in Warsaw/Poland, and some quick info on a secret little project of mine.
BIVBlog #24: IPv6 Subnet Security
In a reply to the previous episode, Matthias pointed out that while the ramond is a useful tool, it is little if any use against a malicious attacker. Right, but if you let an attacker into a subnet with potential targets, you are in some very serious trouble anyway.
BIVBlog #23: IPv6 Stateless Address Autoconfiguration (SLAAC) Tricks
As promised in episode #22, here are some simple but useful things you can do with IPv6 Autoconfiguration but can’t do with DHCP.
BIVBlog #22: DHCPv6 or Stateless Address Autoconfiguration for IPv6?
In virtually all IPv6 trainings and consulting sessions the question pops up if DHCPv6 or Stateless Address Autoconfiguration (SLAAC) is the way to go. Here’s why you quite likely need both.
BIVBlog #21: Why IPv6 is more than a “network job”
If you think that IPv6 is a “network job”, you are in for a nasty surprise: The fun really only starts once the network provides IPv6 and you have to make your applications IPv6-aware. And even that’s not primarily a technical job…
