CIDR is a method for assigning IP addresses and defining IP address ranges more flexibly than the older class-based addressing methods. It allows network administrators to allocate IP addresses in smaller, more efficient blocks, which reduces address wastage. Below is a comprehensive list of all IP addresses within the CIDR block 133.74.128.0/18.
RDAP stands for Registration Data Access Protocol. It is a protocol used to access and retrieve registration data for internet resources such as domain names, IP addresses, and autonomous system numbers. RDAP has several advantages over the WHOIS protocol, including support for internationalization, secure access to data, and the ability to provide differentiated access to registration data. Here is the RDAP raw data for 133.74.128.0/18.
