Generally, when we think about network information, we consider IP addresses, which are an integral part of the Internet. Anyhow, there is another term that is significantly important: autonomous number system.
Autonomous system numbers (ASN) are unique identifiers that are globally available and enable autonomous systems to exchange routing data.

Generally speaking, an autonomous system (AS) is a group of IP prefixes with a clearly defined external routing policy. Each autonomous system must have a unique identifier to interact with the others. There are two types of autonomous system numbers: public and private.
For systems to exchange information over the Internet, public ASNs must be in place. We probably use private ASNs when a system communicates only with a single provider using the Border Gateway Protocol (BGP).
Many Internet users don’t know the ASN networking technique. If you’re one of those, this article will guide some basic techniques used in ASN networking.

What is ASN and its Types?
Autonomous systems (AS) are collections of connected Internet Protocol (IP) routing prefixes under the control of one or more network operators for a single administrative entity or domain that has a clearly defined routing policy.
The Autonomous System Number or ASN is a number assigned by the Internet Assigned Numbers Authority (IANA) to autonomous systems (also called AS because they are a collection of IP networks with independent routing policies).
Autonomous system numbers (ASNs) are accessible worldwide and can identify autonomous systems on the Internet, allowing the AS to share information with its neighbors.
It should be noted that ASNs are represented in two formats: two bytes and four bytes.
There are 16 bits in a two-byte ASN. ASNs are allowed in the format from 0 to 65535. IANA has reserved a total of 1,023 ASNs for private use. These range from (64512 to 65534).
There are 32 bits in a four-byte ASN. This format contains 232 or 4,294,967,296 ASNs (0 to 4294967295). IANA has reserved 94,967,295 ASNs for private use (4200000000 to 4294967294).
ASNs were limited to 65,535 assignments between early 2007 and late 2008 because of the 16-bit integer dependency. IANA assigned a 32-bit autonomous system in the 2000s to increase the number of AS as the Internet grew. As an example, CloudFlare’s ASN is AS13335.
The ASN system work on the bases of its types. The types of ASN are given is the following:
Types of ANS Network:
- Multihomed:
It is possible to connect multiple autonomous systems but cannot transmit traffic between them. It is the perfect solution if one AS connection fails.
- Stub:
In this form of an autonomous system, there is only one connected autonomous system. For instance, if a network is connected to the Internet via a single connection.
- Transit:
This type of autonomous system communicates with several other autonomous systems. It serves as a link between two autonomous systems.
- Internet Exchange Point:
Internet exchange points create autonomous systems as a result of their physical infrastructure.
How do Autonomous System Numbers Work?
When your autonomous system requires an Internet connection or access to another network, it must use Border Gateway Protocol, which requires manual configuration.
Configuration options include identifying other autonomous systems with which you are forming a connection. ASN is the only means of identifying an autonomous system.
A network of networks makes up the Internet, and autonomous systems comprise the extensive networks that comprise the Internet.
Generally speaking, an autonomous system (AS) is an extensive network or a group of networks with a unified routing policy. A device or computer connected to the Internet is connected to an AS.
How Do I Find My ASN?
An autonomous system number is a unique identifier provided by autonomous systems for exchanging routing information.
Further, most users are unaware of finding the information about their ASN. Many online platforms are available to look up the AS information for those who don’t know about it. But the question is which platform is quick and easy to use.
From our research, we have an iplocation.io/asn-whois-lookup platform. With this platform, you will easily find the desired result in a few seconds. What you need to do
just enter the ASN number in the box and press the button. This tool quickly generates the required result. The best thing about this tool is its user-friendly interface.
