Facebook抓取工具使用了错误的DNS数据>我的网站没有被刮掉 [英] Facebook scraper uses incorrect DNS data > my site is not gettng scraped

问题描述

我最近将我的一个站点(gez​​ondbenjij.nl)移到了一个新的托管帐户.这样就产生了一个新的IP地址.

I recently moved one of my sites (gezondbenjij.nl) to a new hosting account. This resulted in a new IP address.

不幸的是，自从此举以来，Facebook抓取程序无法在新IP地址上找到我的网站.它仍然使用旧的IP.所有DNS设置都是正确的，并且每个浏览器/客户端/工具都在178.22.57.204(gezondbenjijj.nl)上找到正确的站点.除了Facebook .. Facebook刮板登陆到我的旧托管帐户中.因此，我猜他们的主机文件或DNS缓存仍保留着旧数据.即使过了几个星期.

Unfortunately, since the move, the Facebook scraper cannot find my site on the new IP address. It still uses the old IP. All DNS settings are correct, and every browser/client/tool finds the correct site at 178.22.57.204 (gezondbenjij.nl). Except for Facebook.. The facebook scraper lands in my old hosting account. So I guess their hostfile or DNS cache still holds the old data. Even after a couple of weeks.

我已在gezondbenjij.com-> gezondbenjij.nl上设置了域别名，并将旧的托管帐户重定向到此.com域.这样，facebook会通过旁路重定向到正确的网站，但仍然无法抓取该网站.因此，我尝试在Facebook上共享的网址目前不会生成摘要.

I have set a domain alias at gezondbenjij.com --> gezondbenjij.nl, and redirected the old hosting account to this .com domain. In this way, facebook is redirected to the correct site via a bypass, but still is not able to scrape the site. So the URLs I try to share on facebook will not generate snippets at this moment.

有没有办法强迫(或请问)Facebook更新其DNS缓存?我使用了fb URL linter，但无法解决问题.它将仅重置facebook的html缓存，而不重置DNS缓存.

Is there any way to force (or kindly ask) Facebook to update their DNS cache? I used the fb URL linter, but it will not solve the issue. It will only reset facebook's html cache, not the DNS cache..

推荐答案

检查DNS配置中的IPv4和IPv6 IP地址.我有类似的问题，问题是我只更新了IPv4 DNS记录，同时保留了旧的IPv6(Facebook在其工具中使用IPv6).我的托管服务提供商已纠正它，问题已解决.

Check your IPv4 and IPv6 IP addresses in your DNS configuration. I had similar issue and the problem was that I've updated only IPv4 DNS record, while keeping old IPv6 (Facebook uses IPv6 in it's Tools). My hosting provider corrected it and problem was solved.
