Legislating around IP addresses is a dubious idea at the best of times. A legislative approach that embeds specific technical implementations falls foul of an important principle of lawmaking in the tech field, technological neutrality. Professor Chris Reed explains in his book Making Laws for Cyberspace how legislating at too detailed a technical level is likely to create legal uncertainty. Legislation that assumes or mandates specific technology is at risk of impeding new technological developments. Technology-specific law is bad law.
