Folks - 
 
 If you work for a Internet service provider, please check your readiness
 to accept customers with 32-bit ASNs as soon as possible.  While we still  
 have some 16-bit ASNs in ARIN's regional pool, availability is limited and 
 we do not anticipate receiving additional 16-bit ASN blocks from IANA.

 Not being able to use 32-bit ASNs in your network and support systems will  
 inevitably lead to confusion for those customers who are assigned them.

Thanks!
