做網(wǎng)站seo的人都知道蜘蛛爬蟲(chóng)這個(gè)詞，每個(gè)搜索引擎都有自己的蜘蛛，蜘蛛的作用就是爬取各個(gè)網(wǎng)站的網(wǎng)頁(yè)從而收錄到自己的數(shù)據(jù)庫(kù)中供用戶(hù)搜索，蜘蛛在爬取網(wǎng)站的時(shí)候網(wǎng)站服務(wù)器的壓力也會(huì)增大，如果細(xì)心的站長(zhǎng)就會(huì)從網(wǎng)站日記分析各個(gè)搜索引擎蜘蛛爬蟲(chóng)的記錄，有時(shí)候會(huì)發(fā)現(xiàn)有很多ip都在爬取網(wǎng)頁(yè)，有的可能就是假蜘蛛，只要知道官方蜘蛛的IP就可以屏蔽這些假蜘蛛了。

        210.72.225.*

如果發(fā)現(xiàn)下面這幾個(gè)ip段每天只增不減的話(huà)，那就很危險(xiǎn)了，很有可能會(huì)進(jìn)入沙盒或者有被K站的現(xiàn)象。

        218.30.118.102

下面這些ip是抓取內(nèi)頁(yè)收錄的，權(quán)重相對(duì)比較低，爬過(guò)此段的內(nèi)頁(yè)文章不會(huì)很快被放出來(lái)，因它懷疑不是原創(chuàng)文章或者懷疑是采集來(lái)的文章。
