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! /John John Curran President and CEO ARIN
