Re: RFC 2182 considered harmful

You seem to be saying that you don't mind false statements if they're not labelled STD. Perhaps, then, you should look at RFC 1035, which requires two servers for each zone. This requirement imposes unnecessary costs on a huge number of zones; it should be replaced by an accurate analysis of the costs and benefits of various server configurations. > "Must" means that to achieve the ability to withstand a single failure, the > servers have to be dispersed. No. ``Servers must do this, to minimize the chance of foo'' means ``Servers must do this. This minimizes the chance of foo.'' This is what the authors meant, it's what the text means, and it's what a huge number of readers understand the text to mean. So your private misunderstanding of the text really isn't relevant. ---Dan
