Updated DNS zone can’t be seen from the local network


I have updated a domain name DNS zone on 123-reg.co.uk where I bought the domain name. I have only updated blog A record to different hosting(IP)

On my PC home (windows) or another PC in the same network (MAC or phone) when I visit the blog.domain.com still shows old IP address (hosting).

But when I connect to 4g on my phone or try from different network, they visit new IP (hosting)

I did ipconfig /flushdns
I have restarted the router at home.
I have cleared browser cache

Why do you think the reason is? How can I solve this?

Why do DNS changes take 24-48 hours to propagate?

Every domain has two name servers assigned to it and these are the only two name servers that hold records for the domain. However, when another server somewhere else in the world, queries the name servers for DNS records, it will often keep a local copy of the DNS record so that next time it needs to know what IP address the domain resolves to, it already has the answer.

Once changes are made to the actual DNS records on the two name servers that are assigned to your domain, these changes will gradually filter through the other servers in the world so that everything is up to date and it is this process that normally takes 24-48 hours.

What can I do if my ISP DNS servers have not picked up the change yet?

If the DNS servers of your ISP have not yet picked up the change you can change your DNS to OpenDNS.

You should be able to change this in your router, but test locally first.
