Hello,
Yes, the Internet Assigned Numbers Authority (IANA) has reserved the fol-
lowing block of AS numbers for private use (not to be advertised on
the global Internet): 64512 through 65535
The AS number space is a finite amount of address space. It is currently
defined as a 16 bit integer and hence limited to 65535 unique AS numbers.
Over 6900 ASes have been allocated however very few are being
actively routed in the global Internet.
Respectfully,

% Are there "reserved" AS numbers, the same way there are reserved IP
% addresses for non-connected networks?

% Are As numbers considered scarce ? (I think of many small Internet
% providers asking for AS numbers just to peer BGP with more than one ISP).
