AS13911 is an Autonomous System Number (ASN) assigned to TERA-BYTE. An ASN is a unique numerical identifier allocated to organizations that operate independently routed networks on the internet. Each autonomous system uses the Border Gateway Protocol (BGP) to exchange routing information with other networks, enabling data to traverse the global internet infrastructure.
TERA-BYTE operates AS13911 to manage IP address ranges, though this ASN does not appear to be currently announcing routes via BGP. AS13911 is registered under ARIN, one of the five Regional Internet Registries (RIRs) responsible for allocating IP addresses and ASNs worldwide. The ASN was registered on 1999-09-08.
An Autonomous System Number (ASN) is a globally unique identifier assigned by Regional Internet Registries (such as ARIN, RIPE NCC, APNIC, LACNIC, and AFRINIC) to organizations that need to exchange routing information on the internet. ASNs are essential to the Border Gateway Protocol (BGP), which is the protocol that connects all networks on the internet. Every ISP, cloud provider, enterprise network, and content delivery network (CDN) that peers with other networks needs at least one ASN. There are two types: 16-bit ASNs (0–65535) from the original allocation pool, and 32-bit ASNs (up to 4,294,967,295) introduced to meet growing demand.
