Growing Pains: Adding IP Addresses
What's the best way to cope with IP address growth?
Each time we need more public IPs, we end up cashing in all existing addresses for a new, bigger, contiguous block. The bulk of our network must be migrated (a big job) merely to gain a few more public addresses.
Is there not a simple way to keep the old addresses in service while adding a new, unrelated Class C?
For example, could we put our server farm on the private range of 10.x.x.x, and then employ NAT (Network Address Translation) to port those private addresses to multiple Class C ranges delegated to us? I have found firewall boxes that can do NAT, but alas, they support only one public-side subnet. If I understand this correctly, we're back to a single contiguous block -- or, a router and pricey firewall box for each subnet. Argh!
Any help is greatly appreciated.
