Simply put, DNS (the Domain Name System) converts text-based, human-readable domain names like www.liquidweb.com into an IP (Internet Protocol) address like 126.96.36.199. This system also works in an inverse manner and converts IP addresses into domain names. When internet-connected devices communicate, IPs are utilized to find and connect to a specified destination. This simply means that the DNS protocol acts as an “internet phone book” of sorts that translates the text-based domain name you enter in your favorite browser into that device ready IP. Because of the limited availability of IPv4 IP addresses, keeping all the internet-ready devices connected becomes even more challenging. This has caused the rise and proliferation of IPv6 addresses. These IP addresses, which look like “2a03:2880:f127:283:face:b00c:0:25de” are continuing to be more widely used.

The Domain Name Service (or DNS) is the key to the presence of your server on the internet. You are probably aware your domain has an “IP” address, which stands for Internet Protocol; that number is your domain’s literal web address on the internet. A typical IP address is a series of four numbers called octets that are identified like so: 10.10.10.10. You can think of your IP address as being similar to a postal address. The IP address is the exact location where your domain lives. I usually explain it like this;
If you are new to web hosting, you may have heard the term DNS, but you might not be sure what it means or how it is essential to you. DNS is short for Domain Name System, and it is the process by which the whole Internet organizes and easier way for humans to reach websites.
Numbers or IP addresses identify all of the computers/websites connected to the Internet. While computers have no trouble identifying each other using these strings of numbers, it would be challenging for humans if we had to remember a set of numbers for every website we wanted to visit! Fortunately, DNS translates domain names like liquidweb.com to an IP address and back, so all we need to know to find a website is the name. For a more in-depth discussion of the DNS system, see Understanding the DNS Process.
You can use the DNS Tree for a quick, visual comparison of the records that exist on all of your nameservers. Making sure your records match across nameservers and that they match your server is an essential part of troubleshooting possible website issues. If you’re error messages like “This site can’t be reached” or “webpage is not available”, the DNS Tree may help you figure out where the problem exists.
How Do I Check My DNS?
Verifying accurate DNS records is essential for navigating traffic to the correct web server. You can use Liquid Web’s Internet Webhosting Toolkit to view your current, authoritative DNS records. Just go to the toolkit’s site, click on the DNS Tree tab, enter your domain name, and click Submit.
Our servers will query your domain’s nameservers for the most common DNS record types. If a domain is not registered or if no DNS records exist for the domain, you’ll receive an error message indicating that the records are not available. This may suggest that your nameservers are unavailable for some reason, especially if you are hosting those nameservers on a private server.
If you have registered your domain and set DNS records our tool will display the results in an easy to see “tree” of records, organized from most general to most specific.
In our example, we are looking up the records for liquidweb.com, so the tree begins with that domain at the far left of the screen.
The next set of records displayed are the Authoritative Nameservers for the domain. These are the servers designated as the holders of the records for this domain. If you want to change the records for this domain, you must change them on these servers. Changing records anywhere else won’t make reflect DNS changes. Your domain can have one, two, or as many Authoritative Nameservers as you would like but most websites use at least two for redundancy and stability.
The next set of entries in the DNS Tree show the Types of records that are available. DNS record types are unique for each kind of DNS function.
An “A Record” is used to identify primary IP addresses of given domains.
“MX Records” are used for email routing and delivery.
“TXT records” hold additional information about the domain, like SSL validations, DKIM entries, or SPF records.
The final “column” of entries displays the actual DNS record. This is typically an IP address for an “A record”, and domain name for an “MX record”, or a string of text for a “TXT record”. Hovering the mouse over a circle will display all of the information for the record in a pop-out window, including the TTL, Type, and Data.
If you’ve made recent changes to your DNS records, the toolkit may be showing an older, or cached, version of the records. The TTL portion of the record indicates how frequently the DNS system should update its records. TTL is shown in seconds, so a typical setting of 3600 means that servers will be asked to update your records every 6 minutes.
The delay that occurs during this period is referred to as propagation. Some DNS changes, like nameserver changes, can take up to 72 hours to propagate, so if you are going to be making changes to your DNS records, you’ll want to lower your TTL values for a quick update. For more information on reducing your TTLs, see How To: Lowering Your DNS TTLs.

Reading Time: 2minutesIf there is one truth in the world of web hosting, it is that we always need more information. Information about configurations, servers, connections, delivery speeds and networking is essential in troubleshooting and optimizing our web presence. While this kind of information can be gathered from various providers and sites across the Internet, Liquid Web has developed a one stop shop toolkit to gather some of the most vital troubleshooting tools in one convenient interface designed to make your life easier.
Reading Time: 3minutesSites with SSL are needed more and more every day. It’s ubiquitious enforcement challenges website encryption and is even an effort that Google has taken up. Certbot and Let’s Encrypt are popular solutions for big and small businesses alike because of the ease of implementation. Certbot is a software client that can be downloaded on a server, like our Ubuntu 18.04, to install and auto-renew SSLs. It obtains these SSLs by working with the well known SSL provider called Let’s Encrypt. In this tutorial, we’ll be showing you a swift way of getting HTTPS enabled on your site. Let’s get started!

If you need to move files, users, subscriptions, FTP accounts, mail and DNS servers setup through Plesk, this guide will help you successfully navigate the process and come out victorious!
We will be splitting this tutorial into three sections:
Poweradmin is a web-based graphical user interface to interact with PowerDNS. It is released under the open source GPL license. It makes it easy to create and edit zone files and interacts directly with the SQL server. Poweradmin has full support for most PowerDNS features, including all zone types (master, native and slave), supermasters, for automatic provisioning of slave zones and full support for A, AAAA, CNAME, HINFO, MX, NS, PTR, SOA, SRV and TXT record types, validation against RFC’s. It also has user and permission management setup for controlling user permissions with templates. In this tutorial, we’ll be showing you how to install and configure Poweradmin as well as some records.
