The Internet is a network of networks*, and autonomous systems are the big networks that make up the Internet. More specifically, an autonomous system (AS) is a large network or group of networks that has a unified routingpolicy. Every computer or device that connects to the Internet is connected to an AS. Imagine an AS as being like a town's post ...
An AS routing policy is a list of the IP address space that the AS controls, plus a list of the other ASes to which it connects. This information is necessary for routing packets to the correct networks. ASes announce this information to the Internet using the Border Gateway Protocol (BGP).
A specified group or range of IP addresses is called "IP address space." Each AS controls a certain amount of IP address space. (A group of IP addresses can also be called an IP address "block".) Imagine if all the phone numbers in the world were listed in order, and each telephone company was assigned a range: Phone Co. A controlled numbers 000-00...
When networking engineers communicate which IP addresses are controlled by which ASes, they do so by talking about the IP address "prefixes" owned by each AS. An IP address prefix is a range of IP addresses. Because of the way IP addresses are written, IP address prefixes are expressed in this fashion: 192.0.2.0/24. This represents IP addresses 192...
Each AS is assigned an official number, or autonomous system number (ASN), similar to how every business has a business license with an unique, official number. But unlike businesses, external parties often refer to ASes by their number alone. AS numbers, or ASNs, are unique 16 bit numbers between 1 and 65534 or 32 bit numbers between 131072 and 42...
ASes announce their routing policy to other ASes and routers via the Border Gateway Protocol (BGP). BGP is the protocol for routing data packets between ASes. Without this routing information, operating the Internet on a large scale would quickly become impractical: data packets would get lost or take too long to reach their destinations. Each AS u...
IP, or the Internet Protocol, is indeed used for routing in that it specifies which destination each packet is going to. BGP is responsible for directing packets on the fastest route to their destination. Without BGP, IP packets would bounce around the Internet randomly from AS to AS, like a driver trying to reach their destination by guessing whic...
ASes connect with each other and exchange network traffic (data packets) through a process called peering. One way ASes peer with each other is by connecting at physical locations called Internet Exchange Points (IXPs). An IXP is a large local area network (LAN)with lots of routers, switches, and cable connections.
Learn what an autonomous system (AS) is, how it controls IP addresses, and how it connects to other ASes via BGP. Find out what an ASN is and how it identifies each AS.
