关于ipupdate

ttft

我下载了本站老大开发的ipupdate插件，在BFW启动后能更新IP地址(3322的)，但在BFW连续运行2天左右，就不能自动更新了，而且用手动更新也不行，提示：
Checking need for update...
Current IP...: 222.213.**.**
Old IP.......: 222.213.**.**
Updating DynDNS -**.8866.org
nc: members.3322.org: Unknown host Response from www.3322.org

如果此时重新启动一下BFW，就可以更新了，这是什么原因呢？

我已经在精华区回帖了~~
具体原因我也不清楚，没法实验，在我以前的测试、使用过程中，更新是自动的，没有问题。现在的情况不知道是希网修改了什么还是其他什么原因。
下面是具体的代码。你先看看。
