Did you update the records for your website/domain? Such as changes to Nameservers, TXT, CNAME, or move to a new hosting service. Then you have come to the right place to check how your website dns propagating with the roxxdns dns checker tool, which has worldwide DNS servers to check propagation instantly.
What is DNS Propagation
When you make any changes to your websites, such as pointing to another hosting service or updating records, the updates, or the propagation, doesn’t happen instantaneously and may take several hours or even days to complete depending on your hosting service. This is what we call DNS propagation, and it greatly relies on your website’s type and scale.
How Do DNS Records Propagate
Suppose you made some updates to your website; say, you added a new record in advanced DNS (Domain Name System). However, not all visitors across the world will be able to see this change instantly, and depending on their geographical locations, any change in your DNS name server may take upto 72 hours before it reflects globally.
In other words, DNS records propagate by prompting every Internet Service Provider (ISP) node across the internet to update their cache data.
Depending on the volume of changes on your website, some of your visitors might still be redirected to an older version of your website once the nameservers change. In contrast, users near or within your geographical location may instantly see the updates. Remember TTL you read a few paragraphs back? Once an update is made, TTL is usually an approximation used to speed up future updates. Changes on your website won’t return until this time expires.
Type DNS Record Can Be Checked With RoxxDNS
However, owners can check DNS propagation for common types such as:
| Record Type | Function |
|---|---|
| A | The most common record types, used for pointing any domain to specific IP addresses |
| AAA | Similar to A records; however, it specifies an IPv6 address of any given server rather than IPv4 |
| CNAME | Also known as alias record types, and they are often used for subdomains such as www |
| NS | Name Server records store authoritative nameservers such as enterprise or government portals |
| TXT | Text records are primarily beneficial for configuring settings such as SPF and DKIM records |
| PTR | Pointer records are used for checking whether any mail server matches the IP address it’s using |
| CAA | Certification Authority Authorization specifies which CAs are permitted to issue certificates |
| SOA | Start of Authority records stores information about domains such as the email address of its admin |
| SRV | The DNS Service records that specify hosts and ports for services such as VoIP and messaging |
| MX | Mail exchanger records used to set email servers and their priority across the globe |
DNS Propagation Delay
Don’t get irritated by the fact that DNS propagation takes “up to” 72 hours to reflect any modification. Depending on the scale of your website and the volume of updates, it may get completed instantly. However, there’s no defined number on how much time DNS propagation takes. This can be anywhere between a couple of minutes to 72 hours. Yet, there are other considerations, such as TTL settings, that may delay the DNS propagation of your website.
DNS Cache: I call TTL the expiry date of DNS data in the cache of local servers or DNS resolvers. When this duration ends, the local servers remove existing DNS records and request another DNS lookup to fetch new info.
Internet Service Provider: ISPs are overlooking TTL rules and keeping DNS records even if TTL has expired. This induces additional delays in DNS propagation and results in conflicting requests within resolvers.
Domain Name Registry: Once you update the nameserver of your website, the changes need to be made higher up in the DNS hierarchy. As an example, for “.com” domains, the nameserver change must be updated in the TLD.
How Can Be Reduce DNS Propagation Time?
The majority of factors affecting the speed of your website’s DNS propagation, such as geographical location and DNS hierarchy, are outside your control, with conflicting policies of ISPs and DNS providers. However, there are still some simple ways to speed up your DNS propagation, which in many cases, will significantly enhance your website’s performance across the globe. Keep in mind that these methods are not guaranteed to work or improve your site.
- The first technique of avoiding TTL delays of your DNS server is to update your records a few days in advance.
- If you see varying DNS results, you may consider flushing your DNS cache or trying other DNS servers.
Why is DNS Not Propagating
The most prominent reason for your DNS info not propagating is that you are probably using your ISP’s DNS for your website.
