^^ What Lazza said.
Login to your control page on clueless, then click the link for "Change preferences, password, RIPE details, reverse DNS etc..."
Set Reverse DNS to "auto", and delete everything except your name under RIPE info.
That's how mine's set and IP2Location doesn't show any details for me personally.
I also notice it shows completely the wrong location for me anyway, but I suspect that may be down to my IP address having been previously assigned to someone else.
Netgear's still hanging on to my line much better than the Zyxel by the way - thanks for that tip
