Dns not updating from other dns
If it's the IP address of the new server, probably, the DNS propagation is complete for you.
If the IP address belongs to the old server, you need to wait for the DNS propagation to complete.
Once A record has been updated, wait up to 30 minutes and change the nameservers for your domain.
As a result, your domain will be resolved to your previous host from the places where the propagation has not been completed yet and to a new one – from the places where it has already passed.
After that, the request is sent to the first receiving point in the USA – New York, NY and ultimately, to the ISP in Phoenix, AZ.
From there, the request goes to the upstream provider in Rome, Italy, then connects to the ISP in Hamburg, Germany.
So your computer starts by checking local DNS cache, then the request is sent to your local Bari ISP.
How to check if DNS propagation has completed for you? Due to DNS caches of different levels, after the nameservers change, some of your visitors might still be directed to your old server for some time, whereas others can see the website from the new server shortly after the change. When you open your domain in a web browser, your request is not going to the hosting server directly, it has to pass through several ISP nodes first.
Then, ask them to do two things: is pointing to by making the following changes to my DNS settings: 1) CNAME Name: www Value: sites.2) A record Name: Value: 34.2 Please update the existing A record and do not create another A record.
Once the records are added, you will be able to check your website by typing its name in the browser.
The major disadvantage of this method is that only you will be able to work on your website in the new location, other users might still see and use your website working from the old server.
This guide will help you to get the general information about DNS propagation and provide you with the answers to the following questions: 1. If it is not there, it looks it up and saves it in order to speed up the loading next time and to reduce the traffic.
Here is an example of the request trace – the number of ISP nodes and their location will vary in each particular case: Each of the ISP nodes checks its own cache to see if it contains the DNS information of the domain.
