More than one hosting providers always means discontinuous
IP-blocks, per CIDR. Remember the big discussion of about 6 weeks
ago, WRT CIDR and peering? If he wants to do this, he's either
going to have to burn a portable /19, or two portable /24's.
In most cases, burning the /19 will be required, depending on
level of prefix filtering, along with negotiatiing up-stream
peering relationships.
