Makes sense...the simplest way to go about this is to get an ASN of your own
and a portable IP block. If that isn't practical (the IP black that is),
you can opt for getting separate Public LAN IP subnets and doing NAT
overload for the LAN traffic, and static NAT for the web servers, especially
if you have some sort of DMZ built.

Joe,
Currently our IP address space is coming from our provider but changing is
not a big deal since the name of the company, website, etc is changing. We
are going to host a couple of web sites and allow business partners to
access data via an Internet app.

The other question is what the traffic flow is like, and what routes you
plan to announce out to the Internet. It looks like all of your address
space is being provided by the current provider. Is this mainly foro
outbound Internet access, or are you planning to host the web sites and such
that will require public IPs?
