I have not used dynamic DNS in a very, very long time. I think the last time was back at the end of the 90’s or the beginning 00’s. Most (if not all) of the services I used at the time do not exist anymore. I happily noticed that my DNS and domain provider offers a DynDNS service.

I read and hear a lot about Wireguard the last couple of weeks. Even Linus Torvalds seems to like it – and praise like that is not easy to achieve. When people say so many good things about it, I should give it a try. I was looking for an OpenVPN alternative anyway.

Since I started using the Cisco AnyConnect VPN Client, I had DNS issues. I could not fully figure out why this happens on my system, but all signs lead to an issue with scoped DNS queries on macOS. Whenever the VPN is established, macOS uses the wrong order to resolve DNS entries.

I recently created several Virtual Machines on my new Hetzner server as part of my migration efforts from DigitalOcean to my self-hosted ESXi hypervisor. I don’t migrate my VMs and services away from DigitalOcean because I am not satisfied with their service, quite the contrary in fact. I am doing it because my own self-hosted hypervisor allows more flexibility for my learning and testing efforts.

IPv6 gets more and more important. I think 2016 will be the year when it get’s adopted on a large scale and finally will start to be mandatory with every new Internet connection — at least in Dual Stack configuration. My web and DNS servers are available via IPv6 for a while now.
