Do any IP addresses have security so they cannot be used by a hacker to access secure pages? For example, could a hacker spoof a Facebook IP address to enter someones profile page and make changes as an administrator?
My facebook profile was hacked twice and the IP addresses both came from the Facebook office in Singapore. I'm wondering if someone hijacked these IP Addresses so they could access my account and make administrative changes to my profile, which is what occurred.
I was under the impression that companies like Facebook would have strong security restrictions to prevent people from hijacking their identity.
