ITLv6TF Spring 2005 IPv6 Status Report

1. ITLv6TF Spring 2005 IPv6 Status Report Todd Deshane, Patty Jablonski, Sarah Jozefiak, Creigh Long, Scott Mead, Jeff Ward

2. IPv6 Project Goals • Learn about IPv6 • What resources are already out there? • What are some of the other IPv6 projects? • Determine how to get IPv6 addresses • 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?

3. Types of IPv6 Addresses • Intrasite Automatic Tunnel Addressing Protocol (ISATAP) • FE80: addresses (link-local address) • IPv6 address that contains an embedded IPv4 address • “6to4” • 2002: addresses • IPv6 address that contains an embedded IPv4 address • 6Bone • 3FFE: addresses • Will phase out in June 2006 • For testing only, was meant to be temporary • Freenet6 • 2001: addresses • Uses production IPv6 addresses so that its service will continue after 6Bone phases out

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

5. 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

6. 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 • anon.freenet6.net – anonymous mode

7. Radvd • Router Advertisement Daemon • Runs on a Linux machine that is acting as an IPv6 router • Listens to router solicitations and answers with router advertisement messages • Stateless autoconfiguration

8. DHCPv6 • DHCP version 6 • Client and server pair • dhcp6c and dhcp6s • Dibbler • Portable DHCPv6 (works on Windows and Linux) • Stateful autoconfiguration

10. Radvd Linux IPv6 router Stateless autoconfiguration DHCPv6 Linux DHCP client/server pair Stateful autoconfiguration Which To Use?

11. 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 • Where to get an IPv6 address • Buy a range of them from an Internet registry • Get it from your Internet Service Provider • Get it from an IPv6 tunnel broker (for free)

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

13. 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 • 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
