3. Representation of AS Number Values

To avoid confusion, a single textual notation is useful for documentation, configuration systems, reports, and external tools and information repositories. The decimal value representation, or "asplain" is proposed as the textual notation to use for AS numbers.

The "asplain" representation represents the number as its decimal value, without any field delimiter, corresponding to the lack of any internal structure required by the use of AS numbers in the inter-domain routing context.
