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),
