Private DNS server – Everything you need to knowPrivate DNS server – Everything you need to know

The use of a Private DNS server is extremely useful. Today, we’ll look at why it’s important and how to put it into practice. But first, let’s go through what it’s all about.

Private DNS server: What does it mean?

As the name implies, a Private DNS server appears to be something personal. It serves as a conduit between your network and the Domain Name System server, preventing data from being intercepted. It’s a DNS network that isn’t connected to the public DNS. Consider it a little private library with a small book collection. This has both benefits and drawbacks. Yes, certain types of books will be unavailable to you. However, there is one advantage: no one will know what you are reading because your library is private.

Private is also known as DNS over TLS (Transport Layer Security) or DNS over HTTPS (Hypertext Transfer Protocol Secure). This is because all DNS queries are encrypted when using DoT (DNS over TLS) or DoH (DNS over HTTPS). As a result, suspicious third parties will have a much more difficult time snooping on your web activity.

Advantages

A Private DNS server offers a plethora of advantages. We’ll simply look at one aspect of them. Here they are:

  • Additional DNS zones and records. You can host as many DNS zones, and DNS records as your server can support. You will be able to use as many DNS records as you require (A, AAA, SOA, PTR, MX, TXT, CNAME, etc.).
  • It ensures your safety! This is arguably the most crucial advantage of the Private DNS server. If you use a public DNS server, you may be more vulnerable to DoS and DDoS attacks. This is exceedingly unlikely to happen if you use a Private Domain Name System server.
  • Almost all premium services are available. Yes, nearly all premium options are provided on the Private Domain Name System server. It could, for example, have Secondary DNS and Dynamic DNS.

How can you implement a Private DNS server?

Setting up your own Private DNS server is simple. However, the technique varies based on your device (computer, smartphone, Operating System, etc.). To recap, you must configure a DNS address on your device to activate Private DNS. Furthermore, having direct links to a third DNS server with DoT or DoH capabilities would be excellent.

Conclusion

Let’s do a review. First, a Private DNS server is really advantageous. It helps to improve security. In addition, with it, you have more DNS zones and records. As a result, installing a Private DNS would be beneficial to businesses. Its employees are safe, the network is secure, and criminal actors will be unable to “probe” or “scout” their network or communications. Furthermore, Private DNS can operate with little or no management once correctly configured. So having it implemented is worthwhile.

DNS record types: 5 Most Popular ExamplesDNS record types: 5 Most Popular Examples

In this article we will take a closer look at the 5 most popular DNS record types. DNS records are text instructions. The computers need them to associate the domain names with their corresponding IP addresses.

A record

The first one from our list is the A record or also known as Address record. It’s definitely the most well-known DNS record type. We use A record to direct or point a hostname to its IP address. When we talk about it, we’re talking about IPv4 addresses (32-bit). And a newer AAAA record type that uses IPv6 addresses (128-bit).

As a result, your site’s A record will include the domain name/host (example.com), as well as the host’s location (IPv4 address), type (A), and TTL (time to live). It’s the most often utilized DNS record.

SOA record

The second one is the Start Of Authority record or SOA record for short. It is the one that is critical to understand. Why? Because it depicts the Start of the Authoritative DNS zone. This DNS record offers a lot of helpful information for the DNS zone. This DNS record is necessary if you want your network to function smoothly and without problems. It directs traffic to the primary DNS server. The DNS administrator’s information and contact information are stored in the SOA record. It also contains a number of parameters, such as the domain serial number. It’s important to note that each DNS zone should only have one SOA record.

PTR record

The PTR record is the following one. You can frequently find it as a Pointer record. We use it to execute backchecks and to reverse the A record. What is the mechanism behind it? It links a hostname to a specific IP address (IPv4 or IPv6). We need it because the rest of the world’s servers may request verification that an IP address matches a hostname before accepting a service, communicating, or doing anything else. As a result, we routinely employ it in host authentication.

MX record

The MX record, which stands for Mail Exchanger record, is another critical DNS record type. Its purpose is to direct the receiving email server for a given domain name in the proper path. It contains the domain name that points to the incoming mail server’s hostname. We should also note that it must point to a hostname rather than an IP address.

In case of failure, you can generate a backup by setting up numerous MX records with different priorities. It is critical that you are able to receive emails accurately.

CNAME record

The CNAME record is the last DNS record type on our list. Its goal is to identify which subdomain or domain name is the canonical one. For subdomains, we commonly use CNAME records. As a result, DNS administration becomes a lot easier. All of your subdomains will be affected by any changes you make to your domain name. It would be helpful if you just used a CNAME record to point your subdomains to the domain name.

Conclusion

Now you are familiar with the 5 most popular DNS record types – A record, SOA record, PTR record, MX record, and CNAME record. So go ahead and put them into action. Best of luck!
