  • Route RPKI validation April 1st, 2022
    RPKI is a security framework by which network owners can validate and secure the critical route updates or Border Gateway Protocol (BGP) announcements between public Internet networks. BGP is essentially the central nervous system of the Internet and one of its fundamental building blocks. The main function of BGP is to facilitate efficient routing between Autonomous Systems (AS), by building and maintaining the Internet routing table. The Internet routing table is effectively the navigation system of the Internet and without it, traffic would be unable to flow between its constituent networks. Unfortunately, routing equipment alone cannot distinguish between legitimate and malicious routing announcements,...
  • RIPE – Atlas Anchor February 17th, 2022
    We have become an even more integral part of the RIPE Atlas project by hosting an anchor, a device that allows for latency analysis of traffic between autonomous systems.https://atlas.ripe.net/probes/7073/RIPE Atlas anchors play an integral role in the RIPE Atlas network by acting both as enhanced RIPE Atlas probes with more measurement capacity, as well as regional measurement targets within the greater RIPE Atlas network. Anchors are able to perform many more measurements than a regular RIPE Atlas probe, and the large amount of data they collect is made available to everyone. In addition, anchors act as powerful targets that can...
  • MANRS June 20th, 2020
    GOLINE firmly believes in initiatives to protect networks, improve security and resilience of the global routing system. Therefore we decided to support the MANRS project and join as participants.Mutually Agreed Norms for Routing Security (MANRS) is a global initiative, supported by the Internet Society, that provides crucial fixes to reduce the most common routing threats. MANRS offers specific actions via four programs for Network Operators, Internet Exchange Points, CDN and Cloud Providers, and Equipment Vendors. Requirements for Participation Please read the full MANRS Actions document before applying. You can become a participant if you meet these requirements: You (or your company) support...

Internet Autonomous System (AS202032)

Internet Autonomous System (AS202032)

Our Autonomous System has been announced!

On the Internet, an autonomous system (AS) is the unit of router policy, either a single network or a group of networks that is controlled by a common network administrator (or group of administrators) on behalf of a single administrative entity (such as a university, a business enterprise, or a business division). An autonomous system is also sometimes referred to as a routing domain. An autonomous system is assigned a globally unique number, sometimes called an Autonomous System Number (ASN).

Networks within an autonomous system communicate routing information to each other using an Interior Gateway Protocol (IGP). An autonomous system shares routing information with other autonomous systems using the Border Gateway Protocol (BGP). Previously, the Exterior Gateway Protocol (EGP) was used. In the future, the BGP is expected to be replaced with the OSI Inter-Domain Routing Protocol (IDRP).

The Internet’s protocol guideline for autonomous systems, after offering a definition similar to the one above, provides a more technical definition as follows:
An AS is a connected group of one or more Internet Protocol prefixes run by one or more network operators which has a SINGLE and CLEARLY DEFINED routing policy.

What are autonomous system numbers?

Each autonomous system is assigned a globally unique number called an Autonomous System Number (ASN). The number serves as an identifier for the AS and is used when exchanging routing information with other autonomous systems. ASNs are available in both 16-bit and 32-bit format, although ASNs issued before 2007 were all 16-bit.

The Internet Assigned Numbers Authority (IANA) manages the ASN system and coordinates the distribution of ASNs across five global regions. Each region maintains its own regional internet registry, which is responsible for issuing ASNs to individual ASes within that region. The five regional internet registries cover the following territories:

  1. African Network Information Center, or AFRINIC — Africa
  2. Asia-Pacific Network Information Centre, or APNIC — Asia/Pacific
  3. American Registry for Internet Numbers, or ARIN — Canada, USA and some Caribbean Islands
  4. Latin America and Caribbean Network Information Centre, or ACNIC — Latin America and some Caribbean Islands
  5. Réseaux IP Européens Network Coordination Centre, or RIPE NCC — Europe, the Middle East and Central Asia
