IPv6 Project Goals Learn about IPv6 What resources are already out there? What resources are already out there? What are some of the other IPv6 projects? What are some of the other IPv6 projects? Determine how to get IPv6 addresses Where can we get an IPv6 address? Where can we get an IPv6 address? Setup and configure an IPv6 network in the ITL on the second Ethernet cards What software, hardware, and configurations do we need? What software, hardware, and configurations do we need?

Types of IPv6 Addresses Intrasite Automatic Tunnel Addressing Protocol (ISATAP) FE80: addresses (link-local address) FE80: addresses (link-local address) IPv6 address that contains an embedded IPv4 address IPv6 address that contains an embedded IPv4 address“6to4” 2002: addresses 2002: addresses IPv6 address that contains an embedded IPv4 address IPv6 address that contains an embedded IPv4 address6Bone 3FFE: addresses 3FFE: addresses Will phase out in June 2006 Will phase out in June 2006 For testing only, was meant to be temporary For testing only, was meant to be temporaryFreenet6 2001: addresses 2001: addresses Uses production IPv6 addresses so that its service will continue after 6Bone phases out Uses production IPv6 addresses so that its service will continue after 6Bone phases out

IPv6 Tunnel Brokers Used to connect to the 6Bone IPv6 network by tunneling over IPv4 IPv6 Tunnel Brokers Freenet6, Hexago, Migration Broker Freenet6, Hexago, Migration Broker Hurricane Electric Hurricane Electric SixXS (Six Access) SixXS (Six Access) IPng Tunnel Provider IPng Tunnel Provider

Freenet6 Free IPv6 service from Hexago that can support thousands of users Users can take advantage of a permanent IPv6 address and prefix Users can get IPv6 connectivity from anywhere – behind NAT device, outside home network /48 prefix may be assigned to a router, making IPv6 connectivity to an entire network

Freenet6 Uses an innovative model based on the Tunnel Setup Protocol (TSP) Client An IPv6 tunnel is made between the PC or router and the Freenet6 tunnel broker TSP configurations (tspc.conf) broker.freenet6.net – authenticated mode broker.freenet6.net – authenticated mode anon.freenet6.net – anonymous mode anon.freenet6.net – anonymous mode

Answers We created a website of IPv6 resources Other IPv6 projects Moonv6, 6TAP, 6NET, Deep Space 6, KAME, BT Exact, AERAsec, Microsoft Teredo, Miredo (Linux), various European projects Moonv6, 6TAP, 6NET, Deep Space 6, KAME, BT Exact, AERAsec, Microsoft Teredo, Miredo (Linux), various European projects Where to get an IPv6 address Buy a range of them from an Internet registry Buy a range of them from an Internet registry Get it from your Internet Service Provider Get it from your Internet Service Provider Get it from an IPv6 tunnel broker (for free) Get it from an IPv6 tunnel broker (for free)

Answers To setup and configure an IPv6 network Software Software Freenet6 – TSP Client Radvd – daemon DHCPv6, Dibbler – client and server Hardware Hardware Network Interface Card(s), networking equipment Linux or Windows machine(s) with IPv6 enabled Configurations Configurations Always check for conf files and documentation

Future Work Determine how to set a static IPv6 address (in Windows and/or Linux) Test that network interface can have a static IPv6 address before we try to assign an address via DHCPv6 Test that network interface can have a static IPv6 address before we try to assign an address via DHCPv6 Confirmed that IPv4 and ISATAP addresses worked Confirmed that IPv4 and ISATAP addresses worked Final Goal – get the DHCPv6 server and client to work, providing IPv6 addresses on second Ethernet cards in the ITL
