It's not quite that simple. Suppose you're multihomed, have an ASN, and
have /24's from several providers. But, you run all your hosts (perhaps
several hundred or more) behind NAT except for a handful of necessarily
public IP ones (DNS servers, web servers, mail servers, etc.). Say you've
been given 3 /24's from 3 providers, but you only actually use about a /27
of public IPs. My understanding of current rules is that:
1) You don't qualify for PI space from ARIN (unless you're in the
ARIN controlled regions of Africa).
2) 2 of your providers have violated the rules by automatically handing
you a /24 with your leased lines as this is space you don't need and have
no immediate intention of renumbering into.
So, somehow its better that you announce 3 PA /24's into the global table
instead of the 1 PI /24 you can't get. Hmmm
