About TopDN

開發者日誌

我的第一個網域名稱 roga.tw 是在 2005 年購買的，之後因為各種需求，網域名稱愈買愈多。早期域名商只賣網域名稱，不見得會提供 DNS 託管，而我的網域購自不同的域名商，在管理上很是麻煩。 後來我在家裡自行架設 DNS 伺服器管理網域名稱，雖然缺乏容錯移轉機制，網路也不夠穩定，不過這樣也撐了好幾年。 自從 2012/02/27 開始，我寫了一個 DNS 管理程式，並且租了三台虛擬主機來管理我自己的網域名稱（兩台美國，一台日本）。 在程式的架構和系統穩定後，我又幫這個程式寫了網站介面，並且提供網友免費註冊使用，也就是現在的 TopDN。 如果您覺得這個系統對你有幫助，非常歡迎透過 PayPal 贊助我，贊助金額將用於虛擬主機月租費，贊助名單列於本頁 Honor List。
