For an explanation of how to check the ASN or AS Number Whois Lookup (ASN lookup) & IP Address Prefixes, please read the description below.

Check ASN (AS Number) Whois Lookup, or Autonomous System Number, is a lookup tool to find out information on autonomous systems (AS) that are a collection of networks routing groups with an IP prefix (IP Prefixes) which in it has that has an IP group, whether it does it have IP?, or consists of one or more IP Prefixes and is connected by one or more network operators by a large organization, or Internet service provider company (ISP). Each ISP must have an ASN that has been officially registered, and each ISP is assigned a unique ASN as an identity number, the purpose of which is to be able to connect and communicate with each other on the Internet.

With this search tool, you can find out how many IPv4 or IPv6 addresses it has by ASN (ASN Lookup to IP). This will make it easier for you to find more detailed and complete information about ASN, because the ASN information here has all the records containing data and information on the allocation of an IP and AS whose data has been provided by (e.g., ARIN, APNIC, RIPE, LACNIC, AFRINIC). If the AS number of one of the ISPs is found, it will display complete information data from Block AS, ISP AS Name, Origin, Description, mnt-by, BGP, Transit, Peerings, Route Prefix IPv4 or IPv6, ISP Location address, Organization name, contact information such as Tel No, Email, Fax No, IP Owner name, Country of origin and many more. Other important information displayed in these results include the number of ASN (as-blocks) and IP blocks (or IP blocks allocated in the form of IP Prefix and subnet mask) assigned to that ASN. With the ASN WHOIS lookup feature, it will make it easier for you to find out and view identity data about ASN info in details, so you don't find it difficult to find it.

Hopefully, this information will be very useful to you.
