Many network experts argue we're nearing network armageddon, but they've been saying that for years."This all started when Tony Blair was elected. The first time. Yep, thatâ's how long IPv6 has been around, and it’s quite a few weeks ago now." He says smart engineering has avoided many of the problems. "Is there an IPv6 “killer app” yet for smaller networks? No. Is there any reason based on security or ease of management – unless you’re running a 100,000-seat network or a national-level ISP – for you to move up to it? No. Should you start to do a bit of reading about it? That’s about the stage we’re truly at, and the answer to that one is: yes," he says.
