xip dns 服务在我们的实际开发中，还是挺有用的，我们可以基于dns模式方便的进行软件开发，同时
结合nginx 的虚拟主机，可以实现灵活的软件部署，以下是基于coredns 的template plugin 实现一个
简单，但是高效的xip 服务
10.0.0.1.xip.name resolves to 10.0.0.1
www.10.0.0.2.xip.name resolves to 10.0.0.2
foo.10.0.0.3.xip.name resolves to 10.0.0.3
bar.baz.10.0.0.4.xip.name resolves to 10.0.0.4
foo.10.0.0.3.xip.name resolves to 10.0.0.3

效果 
以上支持实现了部分xip服务，但是已经够我们实际使用了，具体其他模式的主要是正则的编写，有空了可以写下
参考支持xip 的一个coredns 配置
dalongrong.com:53 {
log
template IN A dalongrong.com {
match (\D*?)\.?(?P<b>\d+\.\d+\.\d+\.\d+)\.dalongrong\.com\.$
answer "{{ .Name }} 60 IN A {{ .Group.b }}"
authority "dalongrong.com. 60 IN NS ns0.dalongrong.com."
authority "dalongrong.com. 60 IN NS ns1.dalongrong.com."
additional "ns0.dalongrong.com. 60 IN A 203.0.113.8"
additional "ns1.dalongrong.com. 60 IN A 198.51.100.8"
fallthrough
}
