How can YouTube know I'm using a VPN?

Al says that YouTube TV won't let him use a VPN now. Leo says that's because they want to know your location. But how do they know he's using a VPN? Leo says that there's no perfect way to detect a VPN, but if it's being done by a known IP address, that tells the tale. So Google knows what IP address VPN servers are using and some VPNs aren't good at masking it. Try another server or service that rotates IP addresses.
