I used to have an ensecured wireless system which means my signal could be picked up by anybody in my neighborhood. I also know that my Yahoo DSL modem assigns a private IP address to my computer which will ping to my Yahoo account. I have a two-part question:
1) Will my DSL modem assign an IP address to any other computer that uses my wireless system signal?
2) Will that modem-assigned IP address ping back to my Yahoo account.
The reason I ask is because someone had/has been using my wireless signal for some questionable activities and the discovered IP address has pinged back to my account. I no longer have a wireless system to protect my security.
