关于动态域名更新的问题

zheng58

本个在changeip.com 成功注册了一个免费的域名，但是安如下的脚本不能自动更新，在ros的日志里看能成功，但是重启动电脑后changeip.com上的IP还是原来的不变，请问大家帮帮我，global domainname "yourdomainname"（此位应填定什么？是changeip.com吗？）
:global domainzone "yourdomainzone"（此位应填定什么？是changeip给我的域名吗如XX.mywww.biz吗）

:beep frequency=500
:global username "yourusername"
:global password "yourpassword"

:global domainzone "yourdomainzone"
}

:if ([/interface find type=pppoe-out running=yes]="") do={
:beep frequency=500 length=2s

:beep frequency=500 length=2s
