Caller: Scammer posing as Telstra

Called saying they were from Telstra and that my IP address had changed from Private to Public. Knowing I am not with Telstra was the first hint, then technically the information he provided regarding how IP addresses worked was incorrect.... So you know Scam, just hand up.

I will note he had a very fulent access and English was very clear...

Said he was from Telstra and that my IP address was compromised. Told me he’d help me connect to their server so they could fix it
