You shouldn't make wild assumptions.
Even a simple investigation about his person would have quickly
invalidated it, but instead you trust your assumption without bothering
to verify.
Spacenet is probably the first commercial ISP in Germany who offered
IPv6 connections and Gert has always been the head behind this deployment.
Gert's signature more likely comes from the same frustration that all the
people (including myself) have who tryed to use IPv6 about 10 years ago.
We all started with full expectations to get the transistion done in the
next couple of years.
Now about 10 years later and IANA finally run out of addresses and still
IPv6 isn't easily available and if it is available often done in an
almost unuseable way with dynamic addresses and such.
>From an integrators standpoint I could even ask:
Do you deliver unuseable alibi IPv6 to your customers today?
Something I never assumed to happen 10 years ago.
I all goes into the wrong direction with all the last minute deployments
right now.
