Discovering the IPv6 Network Periphery
We consider the problem of discovering the IPv6 network periphery, i.e., the
last hop router connecting endhosts in the IPv6 Internet. Finding the IPv6
periphery using active probing is challenging due to the IPv6 address space
size, wide variety of provider addressing and subnetting schemes, and
incomplete topology traces. As such, existing topology mapping systems can miss
the large footprint of the IPv6 periphery, disadvantaging applications ranging
from IPv6 census studies to geolocation and network resilience. We introduce
"edgy," an approach to explicitly discover the IPv6 network periphery, and use
it to find >~64M IPv6 periphery router addresses and >~87M links to these last
hops -- several orders of magnitude more than in currently available IPv6
topologies. Further, only 0.2% of edgy's discovered addresses are known to
existing IPv6 hitlists
