看看这个DDNS脚本有问题吗

xmaxin

:local Nether
:local Status
:local Ddnshostip
:local Upddns "yes"
:local Ddnsname "用户"
:local Ddnspass "密码"
:local Ddnshost "域名"

:set Ddnshostip [:resolve $Ddnshost]
    :if (([:typeof $Ddnshostip] = "ip")) do={
    :foreach i in=[/interface find type=pppoe-out] do={
        :set Nether [/interface get $i name]
        :set Status [/int get [/int find name=$Nether] running]
        :if ($Status=true) do={
            :if ([/ip rout get [find dynamic=yes static=yes active=yes] interface] = $Nether) do={
                :set Nether [/ip add get [/ip add find dynamic=yes interface=$Nether] address]
                :set Nether [:pick $Nether 0 [:find $Nether "/"]]
                :if ($Ddnshostip = $Nether) do={:set Upddns "no"}
            }
        }
    }
}
:if ($Upddns = "yes") do={/tool dns-update name=$Ddnshost address=127.0.0.255 key-name=$Ddnsname key=$Ddnspass}
