The invention provides a data transmission method and a data transmission device of a virtual network interface card. The method comprises the steps of acquiring a first IP address distributed to a target virtual network interface card by a gateway; detecting that whether the first IP address is in a same network segment with the IP address of a preset network interface card; when the first IP address is in the same network segment with the IP address of the preset network interface card, configuring a second IP address not in the same network segment with the IP address of the preset network interface card for the target virtual network interface card; and transmitting messages via the target virtual network interface card configured with the second IP address. According to the method, when the first IP address configured to the target virtual network interface card by the gateway is in the same network segment with the IP addresses of the other network interface cards, the second IP address in another different network segment is configured for the target virtual network interface card, so that the IP address conflict problem is avoided, the user information security can be ensured, and the information transmission reliability is improved.
