Slide 1

Conveying IPv6, Now Christian Huitema Architect Windows Networking & Communications Microsoft Corporation

Slide 2

Agenda The Opportunity Key Problems The Promise of IPv6 What is Microsoft doing Call to Action

Slide 3

The Opportunity

Slide 4

Key Problems Address Shortage Extrapolating the quantity of DNS enlisted locations shows downright fatigue in 2009 . In any case, the functional most extreme speaks the truth 240 M addresses , in 2002-2003 .

Slide 5

Key Problems Address Shortage Peer to Peer applications oblige Addressability of every end point Unconstrained inbound and outbound activity Direct correspondence between end focuses utilizing various simultaneous conventions NATs are a band-help to address deficiency Block inbound movement on listening ports Constrain movement to “understood” conventions Create colossal boundary to organization of P2P applications

Slide 6

Key Problems Lack of Mobility Existing applications and systems administration conventions don\'t work with changing IP addresses Applications don\'t “reconnect” when another IP location shows up TCP drops session when IP location changes IPSEC hashes crosswise over IP locations, changing location breaks the Security Association Mobile IPv4 arrangement is not deployable Foreign specialists dependence not reasonable NATs and Mobile IPv4? Simply say NO

Slide 7

Key Problems Network Security Always On == Always assaulted! Purchasers conveying NATs and Personal Firewalls Enterprises sending Network Firewalls NATs and Network Firewalls break end-to-end semantics Barrier to sending Peer to Peer applications Barrier to conveying new conventions Block end-to-end, approved, sealed, private correspondence No systems for protection at the system layer IP locations uncover data about the client No straightforward approach to limit correspondence inside of system limits

Slide 8

The Promise of IPv6 Enough addresses 64+64 configuration: 1.8E+19 systems, units accepting IPv4 proficiency: 1E+16 systems, 1 million systems for each human 20 systems for every m2 of Earth (2 for each sqft ) Removes need to extend addresses with NATs True portability No dependence on Foreign Agents Better system layer security IPSec conveys end-to-end security Link/Site Local locations permit parceling Anonymous locations give protection

Slide 9

The Promise of IPv6 Example: Multiparty Conference, utilizing IPv6 P1 P2 Home LAN Home LAN Internet With a NAT: Brittle “workaround”. With IPv6: Just utilize IPv6 addresses Home Gateway Home Gateway P3

Slide 10

The Promise of IPv6 If IPv6 is so incredible, why it is not there yet? Applications Need forthright venture, stacks, and so on. Like Y2K, 32 bit versus “clean address type” Network Need to increase speculation No “push-button” move systems ? applications

Slide 11

What is Microsoft doing Building a complete IPv6 stack in Windows Technology Preview stack in Win2000 Developer stack in Windows XP Deployable stack in .NET Server & upgrade for Windows XP Windows CE arranged Supporting IPv6 with key applications conventions File sharing, Web (IIS, IE), Games (DPlay), Peer to Peer stage, UPnP Building v4->v6 move techniques Scenario centered tool stash.:

Slide 12

What is Microsoft doing IPv6 sending tool kit IPv6 stateless location auto-design Router reports a prefix, customer arranges a location 6to4: Automatic burrowing of IPv6 over IPv4 Derives IPv6/48 system prefix from IPv4 worldwide location Automatic burrowing of IPv6 over UDP/IPv4 Works through NAT, may be obstructed by firewalls ISATAP: Automatic burrowing of IPv6 over IPv4 For utilization behind a firewall.

Slide 13

What is Microsoft doing Recommended Strategies In the home Use IPv6 if accessible, Or utilize 6to4 if worldwide IPv4 address, Or utilization IPv6 over UDP In the endeavor Use IPv6 ISP or 6to4 for outer access, Use ISATAP while updating the system

Slide 14

What is Microsoft doing Addressing difficult issues Domain Names and IPv6 have issues Peer to Peer applications oblige dynamic enlistment of IPv6 location DDNS is difficult to convey safely on the web Workarounds oblige building exchange namespaces or keeping away from names through and through Ease of utilization is an unquestionable requirement Need a simple approach to get Mobile IPv6 locations Need a simple approach to determine names in an IPv6 Ad-hoc system (DNS Server not reachable)

Slide 15

In Summary … We Build Together Microsoft is moving rapidly to empower Windows stages for IPv6 Up to date data on: http://www.microsoft.com/ipv6/Send us criticism and necessities mailto:ipv6-fb@microsoft.com We require your assistance to move the world to a basic pervasive system in view of IPv6

Slide 16

Call to Action Network Providers: Build it and they will come Do not make due with NATs for new outlines Demand IPv6 support on all gear Offer local IPv6 administrations Device Vendors: Design for the less complex, omnipresent IPv6 web Application Writers: Don’t attend to the above Use Windows XP and Windows .NET Server NOW!

Slide 17

Microsoft Vision Empower individuals through extraordinary programming at whatever time, wherever, and on any gadget

6to4: burrow IPv6 over IPv4 1.2.3.4 192.88.99.1 2002: 102:304 ::b… 3001:2:3:4:c… 6to4-A Relay C A Native IPv6 IPv4 Internet 6to4 switch get IPv6 prefix from IPv4 address, 6to4 transfers publicize reachability of prefix 2002::/16 Automatic burrowing from 6to4 switches or transfers Single location (192.88.99.1) for all transfers 2002: 506:708 ::b… B Relay 6to4-B 5.6.7.8 192.88.99.1

Slide 21

ISATAP switch gives IPv6 prefix Host supplements prefix with IPv4 address Direct burrowing between ISATAP hosts Relay through ISATAP switch to IPv6 nearby or worldwide ISATAP: IPv6 behind firewall D IPv4 Internet IPv6 Internet IPv4 FW IPv6 FW ISATAP Firewalled IPv4 system Local “native” IPv6 system B C A

Slide 22

IPv6/UDP IPv6 prefix: IP address & UDP port Servers Address disclosure Default “route” Enable “shortcut” (A-B) Relays Send IPv6 parcels specifically to hubs Works for all NAT IPv6 over UDP through NAT C IPv6 Internet
