and your organization plans to integrate a new email service called anotherservice. Now you need to include it in your SPF record, so that the emails sent from that service's hosts pass SPF authentication. Specifically, use the above value for the Original SPF Record field in the "Generate Safe SPF record" step in the "Safe SPF to the rescue" section.

Then go through all the remaining steps in the Safe SPF process. Once you are done, your new Safe SPF record on yourdomain. com contains all the IP addresses in include:anotherservice. com , in addition to the existing IP addresses. And if there is any underlying change in include:anotherservice.

com , your Safe SPF record will pick it up automatically. For example, if you want to replace someservice. com with anotherservice. com in your SPF record, just update it to:. In another example where you want to remove the mx mechanism from the SPF record, simply update it to:.

Another way to update your existing Safe SPF record is to add the new mechanism directly to your published Safe SPF record.

Note that this approach only applies to adding an additional mechanism, rather than replacing or removing an existing one. If you want to replace or remove an existing mechanism, please use Method 1 described above. This record contains all the IP addresses resulted from all the mechanisms in your original SPF record.

Then you need to add a new service include:newservice. com , you can simply update the SPF record on your domain to:.

So, instead, we use domain names. Think of DNS as your phonebook. Every DNS lookup query is processed through four DNS servers: the DNS recursor, the root server, the TLD nameserver, and the authoritative nameserver.

This adds to your DNS lookup time. Hower, Pingdom caches your DNS once— and upon subsequent tests, your DNS lookup time returns to normal as their servers already know your IP address.

WebPageTest is one of the best tools you can use to find your DNS lookup time as it gives you a complete breakdown of each request. These types of subsequent requests affect your page load time—which then influences your DNS lookup time.

This way, the browser can find your hostname without having to make a new DNS lookup request. When setting your DNS TTL, your host might prefer you set it in seconds , not minutes. DNS prefetching enables browsers to run a DNS lookup in the background while the user is still interacting with the page.

Your best option is either to upgrade or switch to a faster DNS provider. Ideally, switching to enterprise DNS providers like Amazon Route 53 , Cloudflare, DYN, and DNSMadeEasy is a better choice. This is because these large providers have an extensive infrastructure with several points-of-presence around the world.

All of which aid in reducing DNS latency. The CNAME record is a type of DNS record that helps connect your subdomains or alias domains to your main domain instead of an IP. However, during DNS lookup, excess CNAME records increase the time it takes the browser to connect to the main IP of your domain.

Reverse DNS is essentially the inverse of forward DNS. The request determines the domain name associated with an IP address. To confirm the legitimacy of the servers from which messages are being received, email servers frequently conduct reverse lookups.

For this operation to be completed, a pointer record PTR must be created on the mail server. Mail servers rely on these records to determine which IP address is authoritative for sending and receiving mail for the domain in question.

When you visit a website, your browser identifies all resources requiring a DNS query. Then, it awaits the completion of the lookup before downloading any resources. The more lookups a website needs, the longer it takes for the browser to generate its pages. A quick DNS lookup example is provided below to understand the lookup procedure.

For this, it needs the IP address of the server. If not, it inquires with the server in charge. This was allocated through DHCP or is permanently configured. If the server can fulfill the request, it returns the response to the requester. If this is not the case, it contacts another server responsible for the domain.

With the provided IP address, the browser can interact over the IP network with the web server Internet. The Time To First Byte TTFB begins with an HTTP request. Since PageSpeed Insights can not help us determine what is triggering DNS Lookup, we will have to utilize additional tools to isolate and resolve this issue.

It is common knowledge that website loading speed is one of the most important SEO and search engine ranking elements. The quicker your website loads, the higher your search engine ranks.

Specifically, you may see the fundamental web essentials while doing a Google page performance test. DNS lookup times strongly influence how quickly those elements load and, thus, how users experience a website. As technology continues to improve, optimization of DNS lookup times will become ever more important for ensuring great UX.

It is so crucial since more than fifty percent of people choose to leave websites that take longer than three seconds to load. The DNS lookup enters the picture at this stage. If your website can do DNS lookups instantaneously o r as fast as possible, it will improve the LCP, FCP, and TTFB of the webpage, as well as the TTFB of resources on the page, such as images or scripts, or styles.

The DNS will then attempt to retrieve the requested website by attempting to match the entered domain with the IP address of the website. Now, the website you are attempting to access is prepared to load.

And if it takes one second for the DNS lookup page to finish the procedure. It would be far more than what Google suggests. Therefore, it is of the utmost importance to reduce DNS lookups times. Generally, a DNS lookup takes between 20 and milliseconds. Generally, anything between that and under is considered to be very good.

For User Experience UX designers and Search Engine Optimization SEO professionals, too many DNS lookups can be a major issue. As the number of requests a website makes to Domain Name Servers increases, it can slow down loading times significantly, resulting in a poor user experience.

Designers and professionals need to ensure that the number of DNS lookups is minimized whenever possible. In addition, DNS may influence SEO results in a number of ways. Some are evident, while others are less so. As previously stated, DNS resolution might be a lengthy process that will add to the total time the visitor experiences.

There is a significant difference between an average of 20 milliseconds with a good DNS provider from around the globe and milliseconds to milliseconds when everything is left to the domain registrar. If a search engine bot attempts to access your site but is unable to, it will report this event.

First, it will be slower at indexing newly added pages. A DNS provider may provide multiple points of presence PoPs from which you can set name servers.

Additionally, it will boost availability. If the DNS transfer is completed successfully and the required precautions are followed, neither users nor search engine bots should notice any change.

The issue arises only if the TTL values of the preceding DNS records are very high and such DNS records remain in the DNS caches of recursive name servers for an extended period of time. They will continue to point to the outdated IP until the caches are updated, resulting in downtime.

There might be several causes for a lengthy response time, including server load, network unpredictability, race conditions in your JavaScript that affect the load order, etc.

If your website loads inconsistently, you should run a few profiles in the performance tab of developer tools with network throttling enabled to see the results. Taking the time to do a DNS lookup speed test can help ensure your website runs as fast as possible. Pingdom, GTmetrix, and WebPageTest are all powerful tools that allow you to examine the DNS lookup time of your site.

The results will then provide a detailed breakdown of requests to identify your domain name system. From there, you can pinpoint areas that need improvement to reduce loading times and keep visitors engaged with your content. Taking control of the DNS lookup performance of your website is an essential step towards maintaining optimal business operations online.

To test your DNS lookup using Pingdom , visit their tools page and input the URL of your website:. This website has no cache, performance plugins, and many faults.

Scroll down for a more extensive explanation of the DNS lookup problem. This pink bar indicates the DNS response time in milliseconds. While hovering over each file request, you can observe whether files need a DNS search and how long it takes to load.

If you would like to identify what is causing the more prolonged DNS lookup on GTmetrix , type the URL in the test tool:. In the Waterfall tab, hover over specific file requests to see the DNS lookup measured in milliseconds.

The goal should be to achieve a response time of 40ms or less. Despite Pingdom and GTmetrix being great tools, WebPagetest seems to provide more specific results. Go to their website and enter your URL:. DNS lookups can cause significant delays in website loading speeds, which is why preventing unwanted DNS lookups is important.

Fortunately, there are strategies we can use to optimize DNS lookups for our websites and enhance user experience. The following strategies will help you reduce DNS lookups:. Utilizing a high-quality DNS service is the most crucial factor.

There are several free and premium DNS services. When you purchase domain names from prominent registrars like GoDaddy, NameCheap, or NameSilo, you get free DNS. These DNS providers often need to be more active, and as the request size grows, so does the DNS lookup time. Then there are DNS providers like Amazon and Cloudflare, whose POPs are spread over numerous nations.
