Silicon Cockroaches, 'dirty' Ipv4 Addresses and Other Internet Oddities
A few surprising Internet trends were detailed at the recent Internet Engineering Task Force conference, including an expected flood of silicon cockroaches, a term used to describe Internet-linked devices such as radio-frequency identification-powered asset trackers that run free of human control. Internet Research Task Force chairman Aaron Falk said that silicon cockroaches are a key variable in the Internet evolving into a network of things, and he warned that such devices could create naming, security, and management problems for network operators.
Another topic discussed was the predominance of "dirty" IPv4 address space, which refers to unapportioned prefixes used by various organizations to number their internal networks. The concern is that if a network operator begins broadcasting one of these "dirty" IPv4 prefixes, users will be blocked from sites and networks that employ that prefix internally.
Meanwhile, Yanick Pouffary, an IPv6 Forum Fellow, said the European Union will be unable to fulfill its promise of having a quarter of its Internet users migrating to IPv6 by May, although a positive development is an increase of European carriers running trials of IPv6.
