Multiple layers of NAT ???? Little
confusing... Atleast in India, most of the networks now assign Public IP address to the customer, except for some smaller networks that still use some kind of proxy to deliver services, where there is a single layer of NAT. Since, all these networks are those where there are less than 1000 customers, they use 16-bit Block (/16 prefix, 256 × C) 192.168.0.0 ~ 192.168.255.255 giving about 65536 IPs. Again, all of the DSL networks are on Public IP and some of them are even on Q-in-Q with multiple layers of VLANs. (Ofcourse, ideal way to deploy DSL / Broadband networks...)

Can someone confirm this? What address space is being used and how is numbering done? I.e as I have been told the plain standard DLS NATing does not support having the same NAT space on inner and outer, how is that handled?
