Slide 2: overview

overview



geographic database


geographic analysis


IPv6 address space trends

Slide 3: geographic database

geographic database


netacuity
used to use IxMapper from Ixia
proprietary software from Digital Envoy 
provides geographic mapping for single IP address
IPv4 only

netgeo
public query database
provides geographic mapping for IP and AS allocation
future
move from dynamic single query to weekly full database processing
add support for IPv6

Slide 4: geographic analysis

geographic analysis




distance from "line of equality" indicates inequality

IPv6 shows greater equality for First World, but cross below IPv4 for greater ineqaulity in the third.

Slide 5: IPv6 address space trends

IPv6 address space trends


prefix allocations
parse whois databases to track rate of address disappearance

prefix announcements
track rate at which prefixes appear in RouteView's BGP

size of allocations vs size of annoucements

topological diversity
dhynamic IPv6 list to cover announced allocations

track degree to which announced allocations create topological diversity
