An Autonomous System Number (ASN) contact information refers to the contact details associated with the entity or organization that holds and operates a specific ASN. The contact information typically includes the name of the organization, mailing address, email address, phone number, and other relevant contact details. Here is the contact information for AS174.

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 174.

IP addresses identify individual devices on the internet, while ASNs identify collections of IP networks under the control of a single administrative entity. Below is a comprehensive list of all IP details for the CIDR block 2.58.4.0/22 within ASN 174, including the count of domains, nameservers, and mailservers associated with it.
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 AS174.
