Terkadang setelah kita mengarahkan suatu domain ke hosting atau merubah dari hosting satu ke hosting lain, perubahan itu tidak bisa langsung dirasakan. Atau masih tetap mengarah ke domain yang sebelumnya.

Bisanya perubahan dari server satu ke server yang lain lebih lambat daripada proses pemesanan hosting baru, dikarenakan browser di komputer client kebanyakan masih menyimpan cache DNS yang sebelumnya.

DNS propagation itself is the time it takes for the domain to be able to connect to the server. The DNS propagation period itself has various variations, which usually can last up to 1 x 24 hours. If the Domain has passed the Propagation period, then the active domain can be accessed.

Berikut adalah beberapa penyebab Propagasi DNS:

  • Computer Cache: usually the computer will store a cache on the internet, this is what causes changes that cannot be directly detected by the client computer that accesses the website.
  • Internet Service Provider: In this case the DNS propagation period is also influenced by the ISP used by the user. The ISP will make adjustments to the new DNS to be enabled under certain conditions.
