Yes it is possible for IP addresses to be falsified (also known as spoofing). In order to spoof an IP address, a user alters the source of a packet (information sent between computers) so as to appear to be sent from a different location than the actual location.
For this reason, blocking an IP address may not prevent further fraudulent orders from the same fraudster as they can simply spoof a different IP address that has not been blocked. Learn more about IP spoofing.
Note: Turbify provides the IP address blocking feature as is and without warranty of any kind to Merchant Solutions and Store v.1 merchants to be used at the merchants' discretion. Merchants should carefully review the Reverse DNS Lookup information provided before blocking any IP address, as IP addresses may be dynamically assigned to users by certain Internet Service Providers possibly blocking legitimate buyers and not ensuring the fraudster is blocked from ordering. Also, as IP addresses may be falsified, merchants are advised to use AVS and CVV responses to determine which orders to approve, reject, or follow up with the issuing bank.
