Thanks for the answer. So, it seems that all customer's STBs could be put in as many VPRNs as necessary to divide them into groups such that RFC1918 space is never exhausted and each customer could get one (or as many as they request) IP address that's publically routable for their internet connectivity.

Excuse my ignorance, but I'm having trouble finding useful information on what a VPRN (Virtual Private Remote Network) is - I could guess, based on my understanding of VPNs and NAT (as it appears to be used as a NAT replacement in context??), but that might be dangerous - any pointers to useful resources would be appreciated. ---------------------------------------------- My apologies, it stands for Virtual Private Routed Network. It's also known by many other names: RFC2547bis, IP Based Virtual Private Network; BGP/MPLS VPNs, Layer 3 VPNs, etc. Here's a link that looks good, though I haven't read it yet: www.spirentcom.com/documents/760.pdf scott
