IPv6 experience from a large enterprise - Networkshop44
- 1. IPv6: Experience from a Large Enterprise Marcus Keane
- 4. • 1999 Microsoft Research looking at IPv6 • Acquired ARIN IPv6 /32 prefix 2001:4898::/32 • 2005-2006 Microsoft IT started working with IPv6 • 2006-2012 IPv6 collaboration across groups • World IPv6 Day • World IPv6 Launch • Mostly grassroots work
- 5. • Operating systems IPv6 capable • Transition technologies • Security and monitoring • On-premise DCs IPv6 enabled • Internet Access • Peering with AS8075 and Level3 • Advertising /48s out of regional /32s • Enabling IPv6 internet to labs on request
- 6. • Corporate network • 63% of managed hosts are v6 enabled • Approximately 50% of corporate access network is native enabled • 6,800 internal v6 routes, 20,000 internal v4 routes • Example DNS AAAA to A record comparison • This includes teredo… Europe Redmond A – 70009 A – 913,700 AAAA – 69,302 AAAA - 654,734
- 7. • Increased LAN control plane traffic • Rogue RAs • FIB requirements on routers • Incongruent traffic for IPv6 and IPv4 • Fixed by IS-IS • Miscellaneous operational issues - MPLS, DAD, etc. • User training
- 8. • MSIT has no more public IPv4 space • We have no more RFC1918 space • Guest wireless network • Corporate network expansion • We have overlapping RFC1918 space • Azure and online properties • Acquisitions – Nokia • This is getting complicated. And expensive
- 9. • Pilot IPv6-only on corporate network • There is an existing small pilot in Redmond, USA • Works for most applications • Still working on some issues – DHCPv6 related • Pilot IPv6-only on wireless guest network • This works well for iOS/Windows Phone • Still have some issues to solve – Android • Both using: • DNS64 • NAT64
- 11. • Deploy IPv6 to remaining access edge networks • This is being automated • Convert DC apps • Most DC apps are still using an IPv4 VIP • Convert to IPv6 with evolution of application • Deploy Global NAT64/DNS64 • Start Removing IPv4 from access edge networks • Network-of-Things will have to remain Dual-Stack
- 12. • DHCPv6 stateful or SLAAC or both? • MPLS for IPv6 – segment routing? • IPv6 Multicast • Network Management
Editor's Notes
- 1999 Microsoft started using IPv6 within research and development labs and via tunneling across the IPv4-only corporate network Also advertised prefix from 3ffe::/16 network via University of Washington Pacific Northwest Gigapop to 6bone research network Developed global IPv6 addressing plan and migrated ISATAP from Windows servers to Cisco routers
- Native IPv6 Office 365 Xbox.com Microsoft.com Windows update (test) Skype for Business Applications via NAT64; no noticeable performance degradation SharePoint Yammer Bing search Windows RPC/SMB Windows RDP Xbox VOD, video playback
- DNS64/NAT64 placement and redundancy will be crucial
