The IPv6 prefix I got from my ISP in Denmark did not stick, as explained here. Well, Google revealed that my ISP expects IAID to be 1 (one), when requesting a prefix using DHCPv6. The mechanism around IAID is explained in RFC3633. And guess what, the DHCPv6 client in my Mikrotik router requests a prefix with IAID 2 (two), not 1. This IAID is a number associated with the interface, and in my case WAN interface “ether1” has IAID: 2. You can find your IAID as follows: “:put [/interface find where name=“ether1”]”. I have not found a way to change this mapping in RouterOS. RouterOSRead More →

In Denmark, FTTH is common. The fiber-providers each have an area that they connect.

Tax on cars and motorcycles is high in Denmark. So goodbye to Germany’s SUV culture, and welcome to the EV world. I did buy a small petrol car though, but those are getting more and more rare. A lot is written about importing your car to Denmark and that it is better to sell it and buy again in Denmark. Well, if you sell something you don’t want to sell, you loose money, and if you buy the same you loose money again. Selling your big SUV and buying a small car in Denmark makes sense and saves money. But that is not a fairRead More →

After 12 years in Germany, I had the opportunity to start a new job in Denmark. It’s a neighbour country to Germany, so big deal, how different can it be… Well in context of digital economy, Germany and Denmark are not just different, they are night and day. In Germany I once had to leave my wife behind in a restaurant, since they only took cash, and I had to go out and find the nearest ATM (she remembers that one quite well). In Denmark, I have not touched cash money for years. When I bought my car in Denmark, I was handed the keys,Read More →
