IP Whitelisting and IPv6 in Marketing Cloud

Knowledge Article Number 000214027


Internet Protocol (IP) is a system of rules for data exchange between two or more computers, and the Marketing Cloud Login IP Whitelist feature currently supports IPv4.

Note: Not all Marketing Cloud routers support IPv6 addresses, so we recommend only using IPv4 addresses when entering individual IP addresses or ranges.


Differences between IPv4 and IPv6

IPv4 (fourth version of the IP protocol) is the most commonly used version to route traffic across the Internet. IPv6 (the sixth version of the IP protocol) will eventually replace IPv4 and is primarily used for devices other than personal computers (mobile devices, televisions, and other non-computer devices with Internet accessibility).
