Stack's IPv6 project

IPv6 is the successor of the well known Internet Protocol (IPv4) on which the entire Internet depends these days. IPv6 offers more IP-addresses (allowing more connected computers and other devices) and better authentication and encryption methods. M.C.G.V. Stack is the students' computer association of the University of Technology Eindhoven (TUE). We were one of the first groups to actively deploy IPv6 networks and we have been connected with the world-wide 6bone network since late 1998.

On 12 October 2000 we started using official IPv6 production addresses: a SURFnet router in Eindhoven connects us with their national IPv6-backbone.

Nowadays practically all computers at Stack and many others belonging to Stack-members or located on different sites at the campus are talking IPv6 to each other and the rest of the world. We offer IPv6-tunnels to connect Stack members at home. Also, if you maintain a computer on the University Campus with IPv6 support and you want a uplink with the rest of the world, feel free to ask us. For more information, please contact our ipv6 team.

Native IPv6 subnets

IPv6-aware laptops can be plugged in to a native IPv6 (auto-configuration) backbone at several places on the University campus:

• MCGV Stack (DH)
• Spacelabs (EH)

The following campus locations used to have native IPv6 as well; but these are no longer maintained and most likely not functional.

• Chemistry Dept. everywhere (HE)
• ICTheek (aka Open Shop, DH)
• ETSV Thor (EH)

Stack IPv6 number plan

This plan has been set up assuming a 2001:0610:1108::/48 range for the University, using the old numbering plan as a basis.

TUE IPv6 number plan

A /56-network allows for 256 /64-subnets and a /60-network for 16 /64-subnets. A /64-network should not be divided in smaller subnets. This may seem limiting, but keep in mind that within a /64-subnet you can allocate 18446744073709551616 hosts.
