The '''Routing Policy Specification Language (RPSL)''' is a language commonly used by [[Internet Service Provider]]s to describe their routing policies.

The routing policies are stored at various [[whois]] databases including [[RIPE]], [[RADB]] and [[APNIC]]. ISPs (using automated tools) then generate router configuration files that match their business and technical policies.

[https://www.rfc-editor.org/rfc/rfc2622.html RFC2622] describes RPSL, and replaced RIPE-181.

[https://www.rfc-editor.org/rfc/rfc2650.html RFC2650] provides a reference tutorial to using RPSL in practice to support [[IPv6]] routing policies.
