Since the past few days I’ve been needing to authenticate my IP address.. The game tells me it’s a new IP but I’ve only been using my own computer for this. I also have to do this every time I log into the GW2 forums. So why? Is it because I’ve enabled e-mail authentication? I haven’t changed my settings for a long time though.

But for full disclosure, one player in the UK was “logging in from” England, Scotland, and Wales, and he wasn’t ever leaving his living room. So the “dynamic IP” can be a contributor to this.
