I am currently writing a series on BGP and how the Internet works from my perspective as the operator of a small autonomous system, AS200351. In this particular article, I want to talk about the process of getting your own ASN (Autonomous System Number). An ASN allows you to exchange routes over Border Gateway Protocol (BGP) with other ASes, announce your own IP addresses to the Internet, and have control over how traffic flows in and out of your network. There are five Regional Internet Registries (RIRs) in the world, but I will focus on ARIN and RIPE NCC. The choice of RIR affects how you manage your resources and how they can be used. RIPE NCC is considered more hobbyist-friendly, whereas ARIN is thought to be focused on businesses, but the reality is more complex. I will provide a brief overview of how each RIR operates. RIPE NCC is responsible for Europe and the Middle East and is considered more friendly towards hobbyists. They require users to live or have a network presence within their service region. They allocate IP resources into two categories: Provider Aggregatable (PA) and Provider Independent (PI). PA addresses are allocated to Local Internet
