A record: Contains the IPv4 address information of the hostname.
AAAA record: Contains the IPv6 address information of the hostname.
CNAME record: Also known as an alias record, it redirects the sub-domain to its domain, such as redirecting https://www.whodat1.com to whodat1.com.
MX record: Provides information on where the domain's email should be routed and the priority of mail servers.
NS record: Offers information about the authoritative nameservers of a domain.
TXT record: Commonly used for other DNS record configurations like SPF, DKIM, or DMARC records.
What is DNS propagation?
DNS propagation refers to the time it takes for DNS changes to propagate across the internet globally. This process can take up to 48 hours to complete worldwide. Use our DNS Propagation Checker to monitor and track the progress of your DNS changes.
What is DNS resolution?
DNS resolution involves translating a domain name into its corresponding server IP address. Knowing a site's IP address is essential to locate it on the internet. A website may have an IPv4 address (A record), an IPv6 address (AAAA record), or both.
How do DNS records propagate?
When you update DNS records, the changes may take up to 48 hours to fully take effect. During this period, ISPs worldwide update their DNS cache with the new DNS information for your domain.
However, due to variations in DNS cache levels, some visitors may still be directed to the old server's IP for a certain period until the DNS records finish propagating completely worldwide. However, in most cases, visitors will see the updated DNS records shortly after the changes. You can use tools like Dig (DNS lookup) to perform A, AAAA, CNAME, and additional DNS records lookup.
Why does DNS propagation take time?
When you change your domain's nameservers and request to open your domain in a web browser, your request does not immediately reach the hosting server. Also don’t forget to flush your local DNS records. Each ISP node first checks its DNS cache to see if it has the DNS information for that domain. If it is not present, it retrieves the DNS information from the authoritative DNS server of the domain to serve the user's request and saves it for future use, speeding up the DNS lookup process.
As a result, the new nameservers do not propagate instantly because ISPs have different cache refreshing intervals, causing some to still hold the old DNS information in their cache.
If your new DNS changes are not reflecting even after the time interval, it is advisable to perform a DNS health check to ensure your changes comply with standards or consider flushing your DNS cache.
Why is DNS propagation delayed?
ISPs around the world have different caching levels, and DNS clients or servers may temporarily cache DNS record information in their DNS cache. The DNS servers fetch updated DNS information when the TTL (Time to Live) expires.
How does the DNS process work?
For example you enter the URL https://breakn.news in your web browser's address bar.
Your browser sends a DNS query to a DNS resolver, which is typically provided by your Internet Service Provider (ISP). This resolver is also known as a recursive server.
The recursive resolver checks its cache to see if it already has the DNS information for the requested domain name. If it has the information, it returns it to your computer, and the process is completed.
If the recursive resolver doesn't have the DNS information in its cache, it sends a query to the root DNS servers. These servers maintain a database of all the top-level domain names, such as .com, .org, .net, etc.
The recursive resolver contacts the root DNS servers, which respond to the query by providing the IP addresses of the appropriate Top-Level Domain (TLD) DNS servers.
The TLD DNS servers receive the query and refer the resolver to the authoritative DNS servers responsible for the specific domain name being requested. These authoritative servers hold the actual DNS records for the domain.
The authoritative DNS servers respond to the query with the requested DNS records for the domain name.
The DNS resolver caches the recently fetched DNS records, ensuring faster access for future requests, and returns the records to your computer. These records can now be used for the intended purpose, such as establishing a connection to the desired website.
