: 謝謝幾位大大在我上一篇文章的推文
: 因為一些原因，我到昨天才考慮會不會是StatCounter的問題
: 今天重看了後台紀錄，
: 才注意這幾天以來，
: 來源是中華電信的，就只有210.242.215.XX這幾組IP
: 畢竟用中華的人也不少，我網誌也有高人氣文章，不可能只有那位廣告商會來XD
: 而且Visitor Path那邊疑似記錄到我，可是跟我的IP卻不符合
: 剛剛才想到裝ShinyStat驗證一下
: 果然同樣的時間，
: ShinyStat記錄到我的IP，但StatCounter記錄到的還是210.242.215.XX orz
: 很明顯StatCounter不知為何，抓不到中華其它的IP
: 只能在210.242.215.XX這範圍鬼打牆
: 造成一直有人用同一組IP不同方式拜訪我網誌的錯覺
: 不知有沒其它人用StatCounter跟我遇到同樣的情況？
: 真是StatCounter誤我啊...
最近StatCounter又出現這種問題，
我回報問題後，以下是客服回覆：
（若懶得看全文，可只看粗略簡譯：
「中華電信不知為何弄了個transparent proxy,
而且似乎有針對StatCounter的rule，
所以問題出在中華電信，它讓StatCounter偵測結果與眾不同。」）
Hi,
Thanks for your patience. Our senior staff has previously looked into this
and there is nothing we can do about how an IP is reported to us. I hope
that makes sense because it's the truest way to describe the situation -
the IP is *reported to us*.
When it comes to IP detection it's not software each company on the
internet has to put together and program themselves all creating their
own "IP detection logic". These sorts of things have industry standards
and everyone is using something extremely similar if not exactly the
same.
Let me give an example. In the programming language PHP which is
widely used by such sites as Facebook, Google, etc, to get the IP of a
visitor you simply use a code like :
$_SERVER['REMOTE_ADDR']
To get the IP in the programming language Python which is also widely
used it's something like
request.environ['REMOTE_ADDR']
And that's it, there's nothing more to be done. As you can see here there
is no room for error. It's not a big complex program to be tweaked and
have the bugs worked out. IP detection is extremely standardized and a
fundamental part of how the internet works.
*If* there were a glitch in how we record IP's it should be effecting a great
many people as we log an enormous amount of hits per day. But the only
IP's with this issue come from only this 1 network.
The important part is how IP's are setup are part of someone elses
network and configuration. In this case they seem to be running two IP
networks in some unique configuration. It could be that the 210.* range is
part of a proxy network they use for various reasons.
Our domain might be filtered on their network for whatever reason. We
are one of the oldest and most established visitor tracker and sometimes
that gets us on filter list.
I hope this makes sense. If you could relay this information to the other
people on your message boards I would greatly appreciate it.
Regards,
Rory
