Re: /8 end user assignment?

Actually the cable modems and Dsl modems usually have a 10.x address
they are used by the ISP's to access their internal firware. Also on
traces that I have done on both cable and dsl the first hop is
invariably a RFC1918 address.

I had said elsewhere this was unprecedented but was then pointed at 18.104.22.168/9,
22.214.171.124/10 which is Comcast assigned in April. I'm surprised none of these
assignemtns have shown up on mailing lists..
When it comes to Comcast, I'm just an ordinary residential subscriber,
but they don't use NAT for subscriber addresses as best I can tell.
Certainly, I've never been given one, asked about one, etc.
