That is, if you dial my phone number, you can reasonably expect to reach my phone. > With no security at all. Otherwise we would have never heard about "cache > poisoning". Cache poisoning is a problem of poor implementations to handle additional information including glue. > P.S. Just to mention: I liked Internet 20 years ago much more and a bit > nostalgic about it.
