"DNS is the Internet's phone book"

This ceased to be a useful analogy many, many years ago!

I've just read the Internet Society's new paper on DNS blocking, aimed at lawyers.

It is a reasonable primer for anyone new to this area, but probably still pretty hard going if you are not at familiar with this stuff.

It has no discussion of different types of record, which I found odd in a DNS primer, meaning that this sentence irked me:

> DNS resolution only translates a domain name to the IP address of a web server

@neil does this mean they don't have to block cname records, only A/AAAA? Or is it just poorly explained
