Contains one or more IP addresses or blocks of IP addresses specified in Classless Inter-Domain Routing (CIDR) notation. AWS WAF supports /8, /16, /24, and /32 IP address ranges for IPv4, and /24, /32, /48, /56, /64 and /128 for IPv6.
To specify an individual IP address, you specify the four-part IP address followed by a /32, for example, 192.0.2.0/31. To block a range of IP addresses, you can specify a /128, /64, /56, /48, /32, /24, /16, or /8 CIDR. For more information about CIDR notation, see the Wikipedia entry Classless Inter-Domain Routing.
