Some people may not be able to read this post because this blog as
no A record anymore. I don’t care if you don’t have IPv6. It’s 2016.
For those of you who can read this: I’ll try to write some technical
posts about Icinga2, libvirt/kvm and other stuff in the future.
Вообще мужик молодец -- надо кончать с IPv4 уже давно!
