Service providers that NAT their whole network?
- From: Philip Matthews
- Date: Fri Apr 15 15:41:06 2005
A number of IETF documents(*) state that there are some service providers
that place a NAT box in front of their entire network, so all their
customers get private addresses rather than public address.
It is often stated that these are primarily cable-based providers.
I am trying to get a handle on how common this practice is.
No one that I have asked seems to know any provider that does this,
and a search of a few FAQs plus about an hour of Googling hasn't
turned up anything definite (but maybe I am using the wrong keywords ...).
Can anyone give me some names of providers that do this?
Can anyone point me at any documents that indicate how common
this practice is?

(*) Some IETF documents that mention this practice:
- RFC 3489
- draft-ietf-sipping-nat-scenarios-00.txt
