AS number and name

American Registry for Internet Numbers (ARIN) issues Internet number resources for use within its region. An Autonomous System is a connected group of IP networks that adhere to a single unique routing policy that differs from the routing policies of your network's border peers. An ASN is a globally unique number used to identify an Autonomous System. An ASN enables an AS to exchange exterior routing information with neighboring ASes. Sites that do not require a unique ASN should use one or more of the ASNs reserved for private use. Those numbers are 64512 through 65535.

The policies governing AS number allocation and maintenance can be found in the Number Resource Policy Manual.

For example:

AS15169 Google Inc.
