DNS zone transfer is our main topic in this article. This is a Domain Name System term that you should know. What is its main purpose, and which are the different DNS zone transfers we will see today. Let’s begin.
DNS zone transfer – what does it mean
Zone transfer is the process of duplicating DNS information (DNS records) from the Primary DNS zone to the Secondary DNS zone. This enables you to create several copies of your DNS records on other name servers. If one of the name servers dies, you will have more availability as a result of completing the transfer. Furthermore, if you run a global website with users from all over the world and many presence locations, you will benefit from faster DNS resolution (PoPs).
Another important factor to note is that if a name server goes down for any reason, your website will not be damaged (for example, maintenance or a DDoS attack). It will stay accessible and available to your visitors.
If you administer a global website and want to speed up Domain Name System resolution, you might consider conducting a zone transfer to many Secondary zones. With this approach, you’ll be able to put your DNS data (DNS records) in numerous Points of Presence (PoP).
FTP is one of the protocols that are a lot popular. Moreover, it has been around since 1971. In present days, it could be implemented in some interesting situations. So, let’s take a minute to explain a little bit more about it.
FTP (File Transfer Protocol) explained.
File Transfer Protocol, or just FTP for short, is a standard communications protocol used to transfer files between devices over a network. In addition, the two have a TCP/IP (Internet) connection. As a network protocol connecting a user and a server, FTP gives the ability for users to download different files, pages, or programs which are available on other services. When the user requires to download the data to their personal device, they are utilizing FTP.
What is load balancing?
Load balancing is a great and very commonly used method implemented for managing the traffic of a hostname. With it, you are able to effectively and in a coordinated way to spread the incoming network or application traffic through a number of servers.
