Many hosting and access providers like to give each paying customer their 
own IPv4 address, since it simplifies DMCA compliance.  Otherwise the 
hosting provider needs to get into the middle of keeping logs for every 
customer.  Even though SNI allows more than one https site per IP, it does 
not create a division for DMCA purposes.  Often in actual fact, each 
"Customer" has further divided his/her hosting space to host for multiple 
websites, sometimes belonging to other people than the ones paying the 
bill to the hosting provider. This includes each customer using SNI to 
determine the identity of the many websites that each customer is hosting 

/22 in the proposal is a maximum. They would still have to show how they 
intend to use the space in accordance with 4.2.2 if they want more than a 

I say lets try the /22, and if needed reduce it.  Remember sets 
the minimum at /24, so setting it at /24 is a one size fits all policy.

As for NAT and even web hosting, the 64k port limitation is also an issue 
as pointed out by others.  While hosting many sites on a single IPv4 
address can be done, it may not be considered rational when considering 
compliance with many laws that are required, including the DMCA.  This is 
one of the factors that speak against the use of CGNAT for internet access 
customers, unless the customers are divided by port address ranges or like 
means.  Otherwise the ISP has to get into the logging business, which can 
also turn into a big cost center.
