How to check DNS propagation?

Elements that influence the propagation time
During propagation, it is important to keep in mind that TTL, the ISP and the domain registry may cause variations in the normal update timing for the reasons we will see below.
Each DNS record requires a time setting, called TTL ( Time Of Live ), within which the servers must have a chance to cache the data.
For example, if you set the time to one hour, it means that the servers will locally store the record data for one hour. After that time, they will delete it and make a new DNS query to get the updated information.
Setting a shorter time may allow the update to occur more quickly, but afghanistan mobile number example this may result in an increase in nameserver queries, which could negatively impact site performance.
ISP
Your ISP , or Internet Service Provider, caches your DNS record data to give users faster access to your website. Essentially, ISPs do a DNS lookup and show the same result for as long as possible.
Additionally, some ISPs do not follow the TTL settings of DNS records, which may result in the data being updated every two/three days.
Domain Name Registry
If there are any changes to the name servers, the request is taken by the domain name registry, which must update the information in its area and then distribute it. This usually takes a few minutes, but some registries can take hours or even days.
If you do not have the right tools, you cannot be sure that your domain's DNS propagation is complete: in fact, even if the site's status is up to date in Italy, DNS servers in other countries may still have a previous version in memory.
To monitor the propagation process, you can perform a test by launching a PING from your PC and, therefore, verify which sequence of IP addresses is returned in direct resolution. To do this, you must access the DOS command prompt and compose the PING command together with the name of the domain you want to verify. This system allows you to verify the DNS propagation on the nameserver of your Internet connection.
