# IPWhitelistSettings

A model the API reference uses in a request or a response. The operation pages link every field typed as this model here.

Whitelist settings. The address screened is the cardholder IP address, not the address of the
integration calling the API, and a transaction with no resolvable client IP address is skipped.

## Fields
- `allowedRanges` (string): Comma-separated IP addresses or CIDR blocks that pass, for example  `203.0.113.10,198.51.100.0/24`. A cardholder IP address matching none of them is  flagged. An address is only compared against entries of the same IP version, so an IPv4  list never matches an IPv6 cardholder. The merchant screen accepts IPv4 only. Null or  blank leaves the rule doing nothing even when enabled. (nullable)
