Get AS number show IP range, routing and description info
An Autonomous System (AS) is a collection of networks, or routers, administered as a group and sharing a common set of routing policies. AS numbers, the unique identifiers for these groups, are managed along with IP addresses by the five RIRs (Regional Internet Registries). Autonomous System numbers are a vital part of the Internet’s core routing System, Border Gateway Protocol (BGP).
The IP forwarding algorithm, commonly known as IP routing, is a specific implementation of routing for IP networks. In order to achieve a successful transfer of data the algorithm uses a routing table to select a next-hop router as the next destination for a datagram. The IP address that is selected is known as the next-hop address.
In the IPv4 address space certain address blocks are specially allocated or reserved for special uses such as loopback interfaces, private networks (RFC 1918), and state-less autoconfiguration (Zeroconf, RFC 3927) of interfaces. Such addresses may be used without registration or allocation from Regional Internet Registries (RIRs). However, these address ranges must not be routed into the public Internet infrastructure.
