10/6/116Watch Project 1 6Watch: Gauging the Global Rollout of IPv6 Dan Massey Dave Meyer Lixia Zhang Colorado State U. Oregon UCLA
Some Background The global IPv4 address pool, managed by IANA, is exhausted. The regional registries still have some space left, but time is running out. 10/6/1126Watch Project
IPv6 Solves The Problem IPv6 uses 128-bit addresses. v6-compatible hosts need to communicate across and to the v4 network. Dual-stack 6to4 Teredo But global v6 deployment still lagging And North America is behind the curve 10/6/1136Watch Project
10/6/1156Watch Project But only 7K in the current table!
Underlying RouteViews Data RouteViews Part of 6Watch Team Source of Raw Data IPv4 and IPv6 10+ Years of global data Data Cited by Everyone, Hundreds of cites Every major networking conference 10/6/1166Watch Project This funding is essential to RouteViews operations. RouteViews is essential to global research and operations.
Global or Region Reachability Cumulative Routes and Current Routes Differ 25K cumulative compared to 7K current Do different ISPs see different tables? Tracked Prefixes with Reachability Differences At least one peer At least one day Compare Tables With Hurricane Electric Claim HE is close to “center” of IPv6 10/6/1176Watch Project
Comparing RouteViews Tables 10/6/1186Watch Project Track Number of Identical Prefixes Most (5.9K out of 7K) prefixes visible everywhere
The Unreachable Prefixes 10/6/1196Watch Project Many Transient Events But others persist Differences Due to More Specific Routes Doesn’t reflect reachability at control plane, 6spider checking data plane… Remainder are unreachable address space
Unreachability Heatmap Grouped by RIR ARIN (169), RIPE (195), LACNIC (39), APNIC (26), AfriNIC (2) 6to4 + Teredo on right Surprising Results Ipv4 transition sites are in the problem set ARIN (North America) 2nd largest contributor to problem set 10/6/11106Watch Project
Looking Forward Complete data plane monitoring implementation Correlate control plane with data plane to provide a comprehensive overview of IPv6 deployment Working on diagnosis 10/6/1111 email@example.com 6Watch Project
What Shows US is Behind? Why Pick HE As the Center? 10/6/11146Watch Project
Some More Detail on An EyeP Entry 1510/6/116Watch Project
6to4 and Teredo Reachability Both prefixes showed up all 20 days 6to4 (2002::/16) Teredo (2001::/32) Unreachable by two peers Both from the same AS Not a significant reachability issue Possibly a (mis)configuration issue 10/6/11166Watch Project
Is Geography To Blame? Very little geographical bias Except for LACNIC ARIN and RIPE had the most reachability holes Also have the largest v6 allocations Generally not considered deployment leaders APAN (Japanese ISP) Most reachability holes Smallest RIB table 10/6/11176Watch Project
