Understanding WordPress DNS

DNS, or Domain Name System, acts like the internet’s phone book. Instead of remembering complex numerical addresses, you can use simple, memorable domain names to access websites.

When you enter a URL like CanadaCreate.com into your browser, DNS quickly converts that user-friendly name into the server’s actual address, known as an IP address (for example, 192.124.249.166).

This process directs your browser to the precise location of the website’s files on the internet.

A DNS record connects a domain name to its corresponding IP address. These records are stored on DNS servers globally, ensuring websites can be accessed from anywhere.

For WordPress site owners, it’s crucial to understand DNS, as incorrect settings can lead to your site being unreachable, slow loading times, or issues with email delivery.

The good news is that once you understand the fundamentals, managing DNS becomes much easier.

Let’s explore how this process operates behind the scenes when someone visits your WordPress site.

How Does DNS Work?

By comprehending how DNS functions behind the scenes, you’ll be better equipped to troubleshoot problems and make informed decisions regarding your WordPress site’s setup.

Here’s what occurs when someone enters your domain name into their web browser:

• Browser Cache Verification – When you enter www.CanadaCreate.com and press Enter, your browser first checks its local cache to see if it has the IP address from a previous visit. If it finds it, you are taken directly to the website, saving time and reducing the number of requests to the server.
• DNS Resolver Request – If there is no cached record, your browser sends a request to a DNS resolver, which is typically your internet service provider’s server or a public DNS service like Google’s 8.8.8.8. This server acts as your personal DNS helper.
• Root Nameserver Inquiry – If the resolver doesn’t have the answer stored, it queries the root nameservers, which are the internet’s primary directory servers. These servers may not know your specific site but can direct you to the appropriate top-level domain (.com, .org, etc.) servers.
• Final Connection Establishment – After the correct IP address is located through the nameserver chain, it is cached for future reference, and your browser connects to the server that hosts your WordPress site. The website then appears on your screen.

This entire process usually takes only a few milliseconds, but understanding it clarifies why DNS changes may take time to spread across the globe:

Setting Up DNS for Your WordPress Site

Now that you have a grasp of DNS and its operations, let’s explore how to configure it for your WordPress site.

Typically, DNS settings are handled by your domain registrar and WordPress hosting provider. You can access these settings to manage DNS records and modify various types of records.

Keep in mind that the specific settings may differ based on your hosting provider. For this guide, we will use Bluehost as an example.

First, log in to your Bluehost account and navigate to theDomainssection in the left-hand menu.

Next, find your website and click on the ‘Settings’ button.

Then, you will see various domain settings within Bluehost. Scroll down and select the ‘Advanced Tools’ option.

This will expand the Advanced Tools section, revealing additional options.

Here, Bluehost will display the nameservers for your domain along with other records. To manage DNS records, click the ‘Manage’ button next to Advanced DNS Records.

Next, Bluehost will show a warning indicating that only advanced users should modify the DNS records.

Click the ‘Continue’ button to proceed.

The next screen displays various types of DNS records.

You can modify these records to configure DNS settings for your WordPress site.

Some common types of DNS records include:

• Address Record (A Record)This record directs domains and subdomains to a specific IP address.
• CNAME RecordShort for Canonical Name Record, a CNAME record links one domain or subdomain to another domain name.
• MX Record (Mail Exchanger)This record directs emails to the designated server that manages emails for your domain.
• TXT RecordsThese records provide descriptive information about the domain in text format to services like Google Search Console.

How to Update Domain Nameservers

Domain Nameservers are specialized servers that store all the DNS records associated with your domain name, providing DNS information to anyone who requests it.

You can find the nameserver for your website through your WordPress hosting provider or domain registrar. Each nameserver has its own address and can manage records for multiple websites.

Keep in mind that the nameserver address may differ based on your hosting provider or domain registration service.

For instance, if you are using Bluehost, your nameservers will appear as follows:

NS2.bluehost.com
NS1.bluehost.com

Typically, there are two primary reasons for updating your nameservers.

The first reason is transitioning to a new web hosting provider. The second reason is the need to integrate a web application firewall (WAF) such as Sucuri or Cloudflare.

When relocating your WordPress site to a different hosting provider, it is crucial to update the nameserver details. This ensures that your domain directs traffic to the new hosting environment.

Additionally, implementing a firewall on your site through a WordPress WAF plugin will also necessitate changing the nameservers. This is because WAF plugins enhance your website’s security by blocking cyber threats at the DNS level.

The process for modifying domain nameservers varies depending on your hosting provider or domain registrar. You can refer to our guide on how to easily change domain nameservers for more information.

Correctly Configuring Redirections in WordPress

Redirections play a vital role in WordPress DNS configuration. Although redirection does not occur at the DNS level, many domain registrars allow you to establish redirections while setting up your site’s DNS settings.

When migrating a website to a new domain or redirecting a URL, it’s essential to update your DNS records.

Manual redirections can lead to errors, which may cause your WordPress site to redirect to the old domain after migration.

DNS issues are a common cause of redirection problems. If a DNS record is not updated or the DNS server is unresponsive, users may not be able to access the new website URL.

To prevent this, consider using a WordPress SEO plugin like AIOSEO. It features a robust redirection manager that allows you to configure redirects in WordPress and manage full website redirects.

With AIOSEO, you can seamlessly migrate your domain and establish redirects without the hassle of DNS issues. Additionally, the plugin provides a 404 error log and assists in fixing broken links.

How to Update MX Records for Your WordPress Site

MX (Mail Exchange) records inform internet servers where to direct email sent to and from your website’s domain name.

To set up a business email address using your domain name, you will need to modify the MX records.

For instance, if you want to set up a professional email address using Google Workspace with your domain (name@mywebsite.com), you’ll need to modify the MX records to direct all your emails through Gmail’s servers.

You may also need to update or add MX records when using an SMTP provider for sending emails from WordPress. An SMTP service enhances email deliverability and helps prevent your emails from landing in the spam folder.

To modify or add MX records, log in to your WordPress hosting provider or domain registrar account.

For example, if you’re using Hostinger, navigate to the Domains section and find the ‘DNS / Nameservers’ area. Then, you can add a new record in the Manage DNS records section and select MX as the record type.

How to Clear DNS Cache on Your Computer

Have you ever been instructed to flush the DNS cache on your computer?

A DNS cache functions like an address book that stores the IP addresses of all the websites you’ve visited. However, this cached information can become outdated, leading to various DNS-related problems on your WordPress site.

Clearing the DNS cache can resolve many common issues by allowing your computer to retrieve updated DNS information.

The process for clearing the DNS cache differs between Windows, Mac, and Chrome. For example, Windows users can do this through the Command Prompt, while Mac users can use the Terminal application.

ipconfig /flushdns
