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!
