Bar BOF: Impact of NAT444 on content providers

Day:  Tuesday March 23
Time: 17:30
Room: TBD

Inspired by some remarks of Lorenzo Colitti (Google) at the recent
APRICOT/APNIC meeting in Kuala Lumpur, we plan to discuss the value
of a short draft aimed *specifically* at content providers, to describe
the impact on them and their customers if many of those customers are
trapped behind double IPv4 NAT (NAT444). Clearly the issues are not
news, but they tend to be described in complex general drafts, or
mixed in with proposed solutions or alternatives to double NAT.

Quoting Lorenzo: "...it would be
good to put together an IETF draft that very concisely lists the problems of
NAT444 from the content provider perspective. For example: worse geolocation
for targeted advertising and streaming content restrictions; higher latency;
IP blocking for abuse/spam causing collateral damage, etc."

The bar BOF agenda is to decide whether to proceed with such a draft and
if so, to identify the people who will write it and the target date.
