- GeoDNS (or GeoIP) is a patch for BIND DNS server software, to allow geographical split horizon (different DNS answers based on client's geographical location), based on MaxMind's geoip (commercial) or geolite (free) databases. The objective of this technology is to enhance the domain name lookup by address resolution based on geographical location of the client. For example a website might have 2 servers, one located in France and one in the US. With GeoDNS it's possible to create a DNS record for which clients from Europe would get IP address of French server and clients from US would get the American one. This makes network access faster and possibly cheaper, compared to directing all users worldwide to the same server or to multiple servers using random distribution, such as round robin. As this technology is DNS based, it is much easier to deploy than BGP anycast. It does not require any support from the ISP and will not break existing connections when the server selected for a particular client changes. However, as it is not intimately tied into the network infrastructure it is likely to be less accurate at sending data to the nearest server. The requester that the resolving DNS server sees is typically not the end user, but the DNS server of the user's ISP doing a recursive lookup, and the recursive DNS server caches the result. As ISPs typically arrange for users to use DNS servers geographically near them, the system usually works nonetheless. (en)
- GeoDNS（或是GeoIP）是BIND DNS伺服器軟體的一套修補程式，其以的geoip（商業）或geolite（免費）資料庫為基礎進行地理劃分（對位於不同地理位置的客戶端回應不同的DNS回答）。 這項技術的目的是透過客戶端地理位置的地址解析來強化域名查詢。舉例來說，某個網站可能有兩套伺服器，其中之一位於法國，另外一個則位在美國。借助GeoDNS，可以讓歐洲的客戶端取得法國伺服器的IP位置，並讓美國的客戶端取得美國的伺服器IP。與使用隨機分配（如輪詢）將全世界的使用者導向至同一個伺服器或多個伺服器相比，這讓網路存取更快，且可能更便宜。 因為此技術是以DNS為基礎，所以它比部署BGP任播要簡單得多。它不需要互联网服务供应商的任何支援，且當特定客戶端選取的伺服器變更時也不會中斷既有的連線。但是由於其與網路的基礎設施沒有緊密的聯繫，因此要將資料傳送給最近的伺服器時可能不太準確。 解析DNS伺服器看到的請求發送者通常不是終端使用者，而通常是使用者的ISP遞迴查詢，並由遞迴DNS伺服器快取結果。由於ISP通常會安排使用者使用地理位置較靠近他們的DNS伺服器，因此這套系統通常仍可正常運作。 (zh)
