An anonymous reader writes "The Internet's addressing authority (IANA) ran out of IPv4 Internet addresses in early 2011. The IPv6 protocol (now 15 years old) was designed exactly for this scenario, as it provides many more addresses than our foreseeable addressing needs. However, IPv6 deployment has so far been dismal, accounting for 1% of total traffic (the high-end of estimates). A recent paper by researchers at the Cooperative Association for Internet Data analysis (CAIDA) indicates that IPv6 deployment may be picking up at last. The paper, published at the Internet Measurement Conference (IMC) shows that the IPv6 network shows signs of maturing, with its properties starting to resemble the deployed IPv4 network. Deployment appears to be non-uniform, however; while the 'core' of the network appears to be ready, networks at the 'edges' are lacking. There are geographical differences too — Europe and the Asia Pacific region are ahead of North America."
