问题:这是一个错误,还是我应该包括.在我的DNS设置?
解决方法 最后的点是正确的.这是一个鲜为人知的事实,但完全合格(明确的)DNS域名最后有一个点.运行DNS服务器的人通常都知道这一点(如果你错过了尾随点,你的DNS配置不太可能有效),但一般公众通常不会这样做.最后没有点的域名不是完全限定的,并且可能不明确.早在1987年,DNS规范RFC 1034就记录了这一点:
Since a complete domain name ends with the root label,this leads to aprinted form which ends in a dot. We use this property to distinguish between: - a character string which represents a complete domain name (often called "absolute"). For example,"poneria.ISI.EDU." - a character string that represents the starting labels of a domain name which is incomplete,and should be completed by local software using kNowledge of the local domain (often called "relative"). For example,"poneria" used in the ISI.EDU domain.
