First experiences with deploying IPv6-Mostly
11-21, 14:00–14:30 (Europe/Berlin), Auditorium

In contrast to the usual dual-stack procedure, IPv6-Mostly can actually save IPv4 addresses. This is achieved by combining a DHCPv4 option (RFC8925) in conjunction with an IPv6 RA extension (RFC8781) and NAT64/DNS64.

I will show how to configure the DHCP server as well as the router and, if necessary, how to configure the clients. We also rolled out IPv6-Mostly in several network segments (wired and wireless) at the end of August and are collecting statistics on client compatibility, which I will also be happy to present.

I am responsible for the operation and technological development of the data network at the Ruhr University in Bochum, which is one of the largest universities in Germany.

I'm also a fan of everything around IPv6 and tirelessly encourage people to finally use it.
