What is IP whitelisting?
IP whitelisting allows you to create lists of trusted IP addresses or IP ranges from which your users can access your domains. IP whitelist is a security feature used for limiting and controlling access only to trusted users. Grow supports a dual stack mode, which lets our platform communicate over either IPv4, IPv6, or both protocols.
Internet Protocol v4 (IPv4)
The Internet Protocol version 4 was designed to be allocated to approximately 4.3 billion addresses. Allocation of IPv4 is globally managed by Internet Assigned Numbers Authority (IANA) under coordination with the Internet Corporation for Assigned Names and Numbers. At present, most of the devices running on the Internet are using IPv4.
Whitelist ALL of the following IPv4 addresses:
52.203.193.180
52.0.63.147
18.209.80.4
