1 Autonomous System Number

2 Internet Assigned Numbers Authority
The Internet Assigned Numbers Authority (IANA) is presently a department of ICANN, a nonprofit private American corporation, which oversees global IP address allocation, autonomous system number allocation, root zone management in the Domain Name System (DNS), media types, and other Internet Protocol-related symbols and numbers.

3 Multicast address GLOP addressing
The allocation method is termed GLOP addressing and provides implementers a block of 255 addresses that is determined by their 16-bit autonomous system number (ASN) allocation

4 Asia-Pacific Network Information Centre
allocating IPv4 and IPv6 address space, and Autonomous System Numbers,

5 Bolt, Beranek and Newman - Computer technologies
BBN was the first networking organization to receive an Autonomous System Number (AS1) for network identification. ASNs are an essential identification element used for Internet Backbone Routing. Lower numbers generally indicate a longer established presence on the Internet. AS1 is now operated by Level 3 Communications following their acquisition of Genuity.

6 Autonomous System (Internet)
That ISP must have an officially registered 'Autonomous System Number' ('ASN').

7 Autonomous System (Internet)
The accepted textual representation of Autonomous System Numbers is defined in RFC 5396 as asplain.RFC 5396, Textual Representation of Autonomous System (AS) Numbers, G

9 Multicast address - GLOP addressing
The allocation method is termed GLOP addressing and provides implementers a block of 255 addresses that is determined by their 16-bit autonomous system (Internet)|autonomous system number (ASN) allocation

10 APNIC * allocating IPv4 and IPv6 address space, and Autonomous System Numbers,

11 Defense Data Network - DDN-NIC
'DDN-NIC' or Network Information Center (NIC) was located at the DDN Installation and Integration Support (DIIS) program office in Chantilly, Virginia. It provided general reference services to DDN users via telephone, electronic mail, and U.S. mail. It was the first organization responsible for the assignment of TCP/IP addresses and Autonomous System numbers.

12 Guifi.net Since early 2011, guifi.net[ guifi.net Autonomous System Number] is connected to the Catalonia Neutral Internet Exchange Point (CATNIX),[ guifi.net connects to CATNIX] which exchanges data with other international telecommunications operators such as Cogent Communications and Hurricane Electric

13 TeliaSonera International Carrier
It is a tier 1 network provider, assigned Autonomous System (Internet)|Autonomous System number AS1299
