An ASN can be associated with one or more CIDR prefixes. This means that an ASN may control one or more CIDR prefixes that will be used to define the IP address space for that autonomous system. Here is the CIDR list for ASN 18558.
| CIDR | NUMS OF IPS |
|---|---|
| 204.26.32.0/20 | 4,096 |

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 AS18558.
