where can I find the IP last used to buy L$ on my account?

the only reason i can imagine you ask this is you think your account is compromised, otherwise it would be your own IP, do not try this yourself but hurry to report this to LL, they will investigate this.

Iiiiii don't think you can.

Here's what the Knowledge Base says about compromised accounts (which I assume is what you think has happened): SL KB: Account Compromised

My understanding is that LL will lock your account temporarily and investigate themselves, but US Dollars/RL money taken probably won't be refunded. If you believe L$ was bought without your permission you should take this up with your payment processor (e.g. PayPal, Credit card issuer) to determine your options.
