I have been running IPv6 and IPv4 concurrently. At Cisco Live San Diego 2019 I shared some of my experiences with Jeffry Handal (I met him initially at CiscoLive Barcelona 2019) and somewhow we ended up talking about IPv6 and how by default you receive multiple IPv6 addresses. To me, that was one of my frustrations, so my network is setup in such a way that it only assigns a single IPv6 address. It appears that such a setup is not very common. So I would like to share with you how my IPv6 network is configured.
