The purpose of a Private DNS server
A Private DNS server, as the name suggests, is something unique. They’re Private DNS networks that aren’t connected to the public DNS. Consider it a personal library with a limited number of books. This has both advantages and disadvantages. However, if you want to read a specific kind of book, you will be unable to do so. Nevertheless, there is one advantage: no one will know what you are reading because your library is private.
The Partial zone transfer (IXFR) is an exciting process, which in some cases it is very valuable. So, let’s explain a little bit more about it.
Zone transfer – definition
The zone transfer process includes duplicating the DNS data with all of the DNS records from the Primary DNS zone to the Secondary DNS zones. Thanks to it, you could create copies of all of your DNS data into one or several name servers. That way, you improve the availability of your domain name. In addition, you make sure that even if one of the name servers is down for some reason, your website is still going to be reachable for your clients. Besides, if you own an international website, the DNS resolution process is going to be quicker, for sure. The reason for that is the DNS data is going to be stored in more than one point of presence (PoP).
What does Email forwarding mean?
Email forwarding is actually a feature that various DNS providers supply. Its main purpose is to redirect the incoming traffic of one email address to another. The interesting part is that it is performing that on a domain level, and there is no need for additional special software.
It is important to understand that it is a separate feature. Moreover, it is different from an email user that transfers a message to someone else or the email forwarding element of Gmail and Outlook.
In case you are administrating the domain name, you are able to redirect the incoming emails from one of the email addresses using the domain name and transfer them to an individual email address.
Secondary DNS – What is it?
Secondary DNS, or also often called Slave or Backup DNS, is a great service that provides a network of DNS servers. They are secondary to your Primary DNS server. Their purpose is to duplicate the Primary DNS zone file automatically. That way, you could establish more points in the world where your DNS records are stored. They are available in a situation when your Primary DNS experiences downtime.
The Ping command explained.
Ping command is an easy-to-use network utility tool with a command-line interface. When you type different commands, you can test many parts of your network, such as the router, computer on the network, a selected domain, or IP address.
The ping command benefits from using ICMP (Internet Control Message Protocol). When you want to make a check, you have to choose a target. In addition to that, you can add options, such as the number of packets, timeout limits, continuous pinging, IPv4 or IPv6, etc.
You will receive an answer with statistics.
The ICMP request is a small packet of data, which your device will send to the target. The target has to bounce it back and provide a response for every ping.
The ping command is available on macOS and Linux within the Terminal application. On Windows, you can use it through the Command Prompt.
