该问题已在ServerFault上得到了详细处理。执行摘要; 千万不能使用.local
或其他虚拟TLD,使用真实的域名。
qmail知名人士dan bernstein拥有一个专门为本地网络选择dnsname的站点(http://cr.yp.to/djbdns/dot-local.html):
It isn't easy to choose a safe top-level local name. The global root
operators add new top-level names every once in a while: for example,
.info was added in 2001, so people using .info as a local name were
unable to reach global .info sites. Software authors sometimes set
aside top-level names; for example, I'm told that Mac OS 9 does something
weird with .local, so it can't access local names in .local. Here are
some reasonable choices of top-level local names:
.0 (good for machine-specific names)
.1
.2
.3 (good for department-specific names)
.4
.5
.6 (good for corporation-specific names)
.7
.8
.9
.internal
看来.home和.corp不会很快被委派!
拟议的通用顶级域名.home和.corp给互联网带来的风险可与千禧年虫(Millennium Bug)相提并论,后者在世纪之交使新兴的互联网变得恐怖,因此应予以拒绝。
同时,本轮申请的所有其他通用顶级域名(gTLD)可能会延迟数月,以减轻它们给互联网用户带来的风险。
