There is a trackback validator plugin which checks if the IP address of the trackbacking server is the same as the URL it is trackbacking for.有一個跟踪校驗插件檢查，如果IP地址，該trackbacking服務器是一樣的網址，這是trackbacking 。 Is this a valid check or will this result in losing many genuine trackbacks?這是一個有效的檢查或將這個結果，在失去很多真正的trackbacks ？

This policy in general will work only when you are directly using the authoring interface of the blogging software like WordPress.這項政策將在一般的工作，只有當您直接使用創作界面的博客軟件一樣，在WordPress 。 However many use offline tools to blog.然而，許多使用離線工具，博客。 Many of the advanced offline tools allow trackbacking from their interface.許多先進的離線工具，讓trackbacking從他們的界面。 Also not all blogs are dynamically generated.也並不是所有的博客是動態生成的。 Blogging software which creates static web pages (like the popular博客軟件造成的靜態網頁（如流行 Thingamablog thingamablog ) cannot trackback from the blog site itself. ）不能跟踪從博客站點本身。 Such blogging software are forced to trackback / pingback from the client interface.這樣的博客軟件被迫跟踪/ pingback從客戶端界面。 Such blogs will therefore be prevented from trackbacking should IP address validation be enforced.這樣的博客因此，我們會阻止trackbacking應的IP地址驗證執行。

Popular blogs are often hosted on multiple servers with DNS based load balancing.受歡迎的博客往往設於多個服務器與DNS基於負載平衡。 Effectively that means the blog will have multiple IP addresses.有效這意味著博客將有多個IP地址。 Suppose n IP addresses used to load balance.假設n使用的IP地址，以負載平衡。 So for such blogs, even when using the authoring interface of the blog on the server side, there is a (n - 1) / n probability that the trackback will fail.因此，這種博客，甚至當使用創作界面的博客就在服務器端，有一個（ -一） /概率，該跟踪將失敗。

Thirdly trackbacking is independent from actual blogging.第三trackbacking是獨立的從實際出發的博客。 So it is logical that advanced blogging platforms (nor or in future) may decide to offload it to other servers for performance or centralization reasons (for multi-blog environments).所以這是合乎邏輯的先進的博客平台（也或在未來的）可能決定卸載到其他服務器的性能或集中的原因（多博客環境） 。

So to summarize I think IP address validation of blogs is an incorrect approach to verify trackbacks (因此，總結，我覺得IP地址的驗證博客是一個不正確的做法，以核實trackbacks （ example plugin例如插件 ) and can result in losing many valid trackbacks. ） ，可能導致失去許多有效trackbacks 。
