How my WhatsApp number is protected from blocking?#

Each GREEN-API instance connects to WhatsApp using its unique IPv4 address.

Therefore, spam activity of neighboring instances does not affect your instance and does not lead to an increase of probability of blocking the WhatsApp number that is connected to it.

IPv4 (Internet Protocol version 4) is the fourth version of the Internet Protocol, which is used to identify devices on a network through an addressing system.
