RE: [lir-wg] AS Number Policy
This has nothing to do with the private AS-number. If an AS number existed in our backbone (public to CW) but not to RIPE NCC's route server. Will that be considered NOT USED ? Ping Lu Cable & Wireless USA Network Tools and Analysis Group W: +1-703-292-2359 E: plu@cw.net

If it is nowhere advertised you could use a privat AS-number...

Definitely there is AS number being used within our backbone but not advertised to public network. So the AS number should be allowed to be registered but not advertised the same way as IP address is treated.

In the documentation for address space provision is made for assigning addresses to organisations that will NEVER be connected to the Internet but require uniqueness from private address space.
Whilst I can't think of a specific example to apply to AS numbers, should this uniqueness be extended to AS numbers that do not show up in the routing table but are very much on-line?
I also recon 3 months to get online although given the length of time it can take a big comapany to integrate a small one lets say 12 months for returning.
Kind regards
Matthew

Could you possibly provide us with more examples in which circumstances someone may need to use AS number from the PUBLIC range instead of using AS number from PRIVATE range in the case when there is no need to advertise any prefixes originated by such AS-number to the PUBLIC Internet (i.e. this AS number will never be visible outside of some private network)? I can remind only one case - some kind of IX, are used by some ASes to exchange routing information localy. Generaly speaking IX-AS may not be visible from PUBLIC, but in the most cases, especialy if we are talking about enterprise networks, same results may be achieved by using AS-number from private range. By way of proof - AS15645 is used for the public Ukrainian Internet-Exchange. Appearance of any prefixes originated by this AS outside of IX members networks violates IX rules and should be avoided. Lets summarise - there ARE circumstances when AS number from PUBLIC range may be requested and used being invisible from the majority of the Internet. It would be nice to mention that in policy and provide some examples. -- Regards, Vladimir.
