I'm having a hard time understanding that sentence. Could you clarify, please: A. Fewer than 97% of DNS resolvers can pass anything other than A/AAAA and CNAME, which means something more than 3% of resolvers pass only A/AAAA and CNAME. This is what I _think_ you mean, which means that n% > broken resolvers > 3%, right? If so, I'd like a citation, though it doesn't sound wrong to me. That we'd have something on the order of 3% of the software deployed everywhere on the Internet be broken ought to be completely unsurprising. B. 97% of the DNS resolvers is the most that has ever been observed working according to specification, and the number may be much lower. This is the rhetorical point I think might be read in. In this case, I think a citation is in order. Thanks, A -- Andrew Sullivan ajs@xxxxxxxxxxxxxxxxxx
