IPv6 has been around for two decades, and yet it is only now making up a meaningful portion of Internet traffic. Reports today find that there are between 10-15 billion Internet-connected devices (each requiring an IP address), yet only 2.8 billion routed IPv4 addresses. The conclusion?

November 1st, 2016

When folks talk about end user or ‘real user’ monitoring, they usually mean injecting code (often Javascript) into an application to measure user behavior and timing.
