WHY ASN IS REQUIRED
What is ASN?
ASN stands for Autonomous System Number. It is a unique identifier assigned to an organization or entity that operates a portion of the Internet’s routing infrastructure. ASNs are used to identify networks and facilitate the exchange of routing information between different networks.
Why is ASN Required?
ASNs are required for several reasons:
- Unique Identification: ASNs provide a unique way to identify different networks and entities on the Internet. This allows for efficient routing of traffic and helps prevent conflicts between networks.
- Routing Information Exchange: ASNs enable organizations to exchange routing information with each other. This information includes the paths and costs associated with different routes, allowing networks to choose the best path for traffic.
- Policy Control: ASNs allow organizations to implement routing policies that govern how traffic is forwarded within their networks. This includes policies related to traffic prioritization, security, and access control.
- Interconnection: ASNs are used when establishing peering or interconnection agreements between different networks. These agreements allow networks to exchange traffic directly, without having to rely on third-party providers.
Benefits of Having an ASN
Having an ASN offers several benefits to organizations, including:
- Control over Routing: ASNs give organizations control over how traffic is routed within their networks. This allows them to optimize routing paths, improve performance, and implement security measures.
- Direct Interconnection: ASNs enable organizations to establish direct peering connections with other networks. This can result in improved performance, lower costs, and increased reliability.
- Improved Security: ASNs can be used to implement security policies that help protect networks from unauthorized access and attacks. This can include filtering traffic, implementing access control lists, and monitoring network activity.
- Enhanced Scalability: ASNs allow organizations to scale their networks and accommodate growing traffic demands. This is especially important for organizations that are experiencing rapid growth or have plans for expansion.
How to Get an ASN
To obtain an ASN, organizations can follow these steps:
- Contact a Regional Internet Registry (RIR): Organizations should contact the appropriate RIR for their region. The RIRs are responsible for allocating ASNs and maintaining the global ASN registry.
- Submit an Application: Organizations need to submit an application to the RIR, providing information such as the organization’s name, address, contact details, and the purpose of the ASN.
- Pay the Application Fee: RIRs typically charge an application fee for ASN assignments. The fee varies depending on the RIR and the size of the ASN.
- Receive the ASN: Once the application is approved, the RIR will assign an ASN to the organization. The ASN will be registered in the global ASN registry and can be used immediately.
Conclusion
ASNs are essential for organizations that operate networks and participate in the global Internet infrastructure. They provide unique identification, enable routing information exchange, facilitate policy control, and allow for direct interconnection between networks. Having an ASN offers numerous benefits, including improved control over routing, direct interconnection, enhanced security, and increased scalability. Organizations can obtain an ASN by contacting the appropriate RIR, submitting an application, and paying the application fee.
