1 Akamai Faster Forward with IPv6 IPv6 Eric Lei Cao Head, Network Business Development Greater China

2 Agenda What is Akamai? Akamai s IPv6 Capabilities Experiences & Lessons Measuring IPv6 Adoption

3 What is Akamai?

4 What Akamai does Makes the Internet fast, reliable, and secure for our customers Used by many of the World s top companies & web properties Solutions include: Web Performance Media Delivery Cloud Security Cloud Networking

5 Traditional Delivery ISP Data center Home Transit Network ISP Mobile 1 or more data centers Connect to 1 or more transit providers Connect directly or indirectly to a myriad of ISPs ISP Enterprise

6 Problems with Traditional Delivery Data center $$ $$ $$ ISP Home Transit Network X ISP Mobile Bad for application owners Bad for users Bad for ISPs ISP Enterprise

7 The Akamai Way Data center ISP Home Transit Network ISP Mobile ISP Bypass middle mile Directly deployed in over a thousand ISPs Enterprise

8 Solving Problems the Akamai Way ISP Data center Home Transit Network ISP Mobile Good for application owners Good for users Good for ISPs ISP Enterprise

9 The Akamai Platform A Global Platform Over 170,000 servers In over 2,400 locations In over 1,300 networks In over 650 cities In 102 countries With Enormous Scale 20+ trillion bits per second 30+ million hits per second 2+ trillion deliveries per day 100+ petabytes per day 240+ Gbps attacks defended

10 Akamai s IPv6 Capabilities

11 Akamai s goals around IPv6 Committed to help customers with a smooth transition Enable customers to make IPv6 content available to users Maintain or improve performance & reliability Deliver content from nearby dual-stack servers Provide IPv6 edge to IPv4 origin translation service Soon: Provide an IPv4 edge to IPv6 origin translation service! Many Akamai products & solutions include robust support for IPv6 Some limitations and feature gaps remain Most products opt-in today More products will dual-stack by default over time

12 How Akamai enables IPv6 Dual-stacked edge servers Customer properties can be dual-stacked Terminate IPv4 and IPv6 connections in server software Can go forwards to customer origin via IPv4 (and IPv6 soon) End-to-end testing recommended and occasional origin changes Akamai Origin IPv4 IPv4 or IPv6 Users

13 IPv6 dual-stacked content on Akamai Many thousands of dual-stacked hostnames on Akamai Over 200 customers have opted-in Major websites, images, videos, downloads, & more Multiple SaaS/IaaS/PaaS resellers and customers dual-stacked with tens of thousands of end-customer properties Thousands of US government websites on Akamai (driven by OMB mandate) Open challenge: how to convince and enable the rest? Complex web properties often need testing & back-end changes

14 Transition to IPv6 for Akamai - History Underlying Foundation Client-to- Edge Edge-to-Origin & Remaining Features IPv6-only Servers IPv6 client-to-edge HTTP support first launched in 2011 Started dual-stacking servers around the globe Since then, actively: Adding support to more products and closing feature gaps Deploying IPv6 in more locations Helping customers dual-stack their sites and content

15 Akamai and IPv6: current deployment status IPv6 now configured and live on Akamai servers in over 95 countries over 460 cities (in all continents except Antarctica) over 560 networks over 1,400 server locations (limited by some of our network partners not yet having working IPv6)

16 Akamai has IPv6 support in Our HTTP(S) edge server and TCP-termination systems Including most features handling, logging, & conveying IP addrs Required custom support in kernel, load balancers, BGP servers, Name server and global Internet Mapping systems Akamai s FastDNS DNS service with AnyCast IPv6 authorities Akamai s Global Traffic Manager Constantly measuring IPv6 global connectivity from locations EdgeScape geolocation database Metrics and monitoring agents Web Application Firewall and Client Reputation systems Many provisioning, reporting, analytics, and support systems.. hundreds of other systems

17 Challenges Shallow IPv6 support is easy, but deep and pervasive takes time Hundreds of custom software systems Reliance on over a thousand network partners Makes IPv6-only Akamai infrastructure less compelling Deep integration with many major Internet properties Interesting technical challenges around every corner

18 Coming soon Deliver content to IPv4 and IPv6 end-users from IPv6-only servers and data centers! Akamai Origin IPv6 IPv4 or IPv6 Users * No committed availability or dates --- contact your account team with interest

19 IPv6 Adoption: HTTP(S) traffic levels Major factors Content availability Client network connectivity Client & CPE devices Date IPv6 Addresses Observed / week IPv6 Addresses Observed / day Akamai IPv6 Requests / Day June 2011 (W6D) 280 thousand 8.3 million June 2012 (W6L) 19 million 3.8 billion June million 10+ billion Dec million 20+ billion Sept billion 211 million 38+ billion Feb billion million 50+ billion More Content x More Clients More Traffic

21 Experiences & Lessons

22 Areas for Content Providers to be careful Systems handling IP addresses may need updates Storing Client IP addresses in a database Example: trying to store a 30 char IPv6 address in a 15 char client_ip database field Auth & session cookies with IP addrs highly problematic Multi-homed or dual-stacked client may use multiple addresses Client reputation, fraud prevention, and auditing IP ACLs, especially in the case of split IPv4-only VPNs IP Geo location Custom client software, such as on mobile devices

23 Other common IPv6 pitfalls Not everything claiming to support IPv6 does so fully IPv6 connectivity still spotty in some areas Pockets of the IPv6 Internet that can t reach other pockets IPv6 PMTUD is a common area for breakage Vendors, end networks, & content providers must regularly test Could benefit from better technology and testing tools Impact (today) limited to small set of users Increased complexity from IPv4 and IPv6 in-parallel

24 Another thing supporting IPv6: Bots! Even in 2011 we observed one set of infected hosts that saw a AAAA record appear and followed it I guess the malware was IPv6-ready? Akamai blocking ongoing probes over IPv6 Over 15 million per day in 2015 from all around the world! Make sure your firewalls support IPv6!

25 Measuring IPv6 Adoption

26 Virtuous cycle Ideally, with better performance over IPv6 than IPv4 More IPv6 Eyeballs More IPv6 Content More IPv6 Traffic More IPv6 Connectivity

27 IPv6 Adoption: Ramping US IPv6 Growth IPv6 in US is a major factor in increased client adoption
