Data Source. During a two-week period in
January 2014, CAIDA researchers collected data
using our distributed measurement infrastructure,
Archipelago (Ark). For the IPv4 map, 74 Ark
monitors in 33 countries on 6 continents probed
paths toward 263 million /24 IPv4 networks. For
the IPv6 map, the subset of 33 IPv6-connected Ark
monitors located in 21 countries on 6 continents
concurrently probed paths toward 3.3 million IPv6
addresses. These measurements covered,
correspondingly, 92.4% of the IPv4 routable
prefixes and 76.1% of the globally routed IPv6
prefixes as seen in the Route Views Border
Gateway Protocol (BGP) routing tables on January
1, 2014.
We aggregated the captured IP-level data to
construct IPv4 and IPv6 Internet connectivity
graphs at the Autonomous System (AS) level. Each
Figure 1. Coordinates of AS in AS core.
Analysis. As in previous years, the IPv6 graph
exhibited faster relative growth than the IPv4
graph. During a one year period from January 2013
to January 2014, the number of IPv6 ASes
increased by 80% and the number of links
between them increased by 63%, while the IPv4
graph gained 9% more ASes and 14% more links.
However, in absolute terms, the IPv4 graph grew
by 3K ASes and nearly 16K new inter-AS links, while
the IPv6 graph added nearly 2K ASes and 5.5K
links.
degrees (number of neighbors) provides
additional insights into the Internet's evolutionary
trends. Candle plots in Figures 2 and 3 illustrate
the distributions of relative AS degree changes
that occurred between 2013 and 2014. Each bin in
those plots either includes all ASes that had the
same degree in 2013 data or spans several degree
values to include at least 25 ASes. For each bin, the
black line in the middle shows the median
percentage of change, the vertical box is drawn
between the 25th and 75th percentile values, and
the vertical line ends at the 5th and the 95th
percentile values.
ranges more than 25% of IPv4 ASes had their degrees
decreasing between 2013 and 2014: the lower end of all
boxes in this candle plot is in the negative area.
Figure 3. In contrast, in Figure 3, the median lines in all
bins are above 0 indicating that between 2013 and 2014
more IPv6 ASes tended to increase than to decrease their
degrees in all degree ranges. Moreover, less than 25% of
IPv6 ASes that had degrees of 4 or more in 2013,
decreased their degrees by 2014. Figures 2 and 3
quantitatively confirm our observation that the IPv6
inter-AS connectivity grew relatively faster than the IPv4
decreased by 22% removing it from the Top 10 group in
2014. In the IPv6 graph, 10 of the 12 shown IPv6 ASes
increased their degree, with a median increase of 70%.
Hurricane Electric (AS 6939) remained the largest IPv6 AS,
increasing its degree from 966 in 2013 to 1740 in 2014.
GEANT (AS 20965) and Biznet (AS 17451) showed the
largest relative degree increase in the IPv6 space,
acquiring nearly 425% and 244% new IPv6 neighbors
correspondingly, and thus entering into the "Top 10"
group. At the same time, Cable & Wireless (AS 1273) and
Global Crossing (AS 3549) saw their IPv6 degree
decreasing by 49% and by 13% therefore losing their Top
10 positions.
This visualization illustrates the extensive geographical scope
and rich interconnectivity of nodes participating in the global
Internet routing system, and compares snapshots of macroscopic
connectivity in the IPv4 and IPv6 address space.
