 An Autonomous System Number (ASN) is a numeric identifier used in the BGP protocol to identify which [autonomous system](https://en.wikipedia.org/wiki/Autonomous_system_%28Internet%29) a particular prefix is originating and transiting through. NetBox support both 32- and 64- ASNs.
 
-ASNs must be globally unique within NetBox, must each may be assigned to multiple [sites](../dcim/site.md).
+ASNs must be globally unique within NetBox, and may be allocated from within a [defined range](./asnrange.md). Each ASN may be assigned to multiple [sites](../dcim/site.md).

+# ASN Ranges
+
+Ranges can be defined to group [AS numbers](./asn.md) numerically and to facilitate their automatic provisioning. Each range must be assigned to a [RIR](./rir.md).
+
+## Fields
+
+### Name
+
+A unique human-friendly name for the range.
+
+### Slug
+
+A unique URL-friendly identifier. (This value can be used for filtering.)
+
+### RIR
+
+The [Regional Internet Registry](./rir.md) or similar authority responsible for the allocation of AS numbers within this range.
+
+### Start & End
+
+The starting and ending numeric boundaries of the range (inclusive).

 The NAPALM integration feature found in previous NetBox releases has been moved from the core application to a dedicated plugin. This allows greater control over the feature's configuration and will unlock additional potential as a separate project.
 
+#### ASN Ranges ([#8550](https://github.com/netbox-community/netbox/issues/8550))
+
+A new ASN range model has been introduced to facilitate the provisioning of new autonomous system numbers from within a prescribed range. For example, an administrator might define an ASN range of 65000-65099 to be used for internal site identification. This includes a REST API endpoint suitable for automatic provisioning, very similar to the allocation of available prefixes and IP addresses.
