Well I must admit that I have not seen that one before. However just because there is a domain out there that is incorrect and will resolve does not mean that we should allow others. The way I reconcile this is that we need a patch for the resolver and I will be sure to mail one to the Internet Software Consortium. There are a number of cases where there are issues with implimentations of protocols, TCP, RMON where they are fixed one problem at a time. > I've always thought that the code that barfs on these names in gethostbyname() > really violates the "be conservative in what you send, and liberal in > what you receive" thought that made the Internet work. Yeah, yeah, BIND > does it, but that's no excuse, either. I sort of agree with you here, however allowing this particular situation to occur has just increased the number of non standard domain names. > What do I know; I was just the first chair of the domain name working group > in the IETF so many years ago before it got fashionable. In that case you will know a hell of a lot more than me and I honestly do not want to contradict you. I was 11 when 952 was written and I do not claim to know the reasons or motivations behind the decisions that resulted in that draft. However the Internet is a great deal different, there are a lot more people with a great deal less knowledge and understanding maintaining things like DNS servers etc. I feel that the live and let live attitude that you expouse worked when people like yourself, Jon Pollard etc were the people controling things. That is just no longer the case. glenn To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
